Stephane Chazelas discovered a bug in the environment handling in Perl.
Perl provides a Perl-space hash variable, %ENV, in which environment
variables can be looked up. If a variable appears twice in envp, only
the last value would appear in %ENV, but getenv would return the first.
Perl's taint security mechanism would be applied to the value in %ENV,
but not to the other rest of the environment. This could result in an
ambiguous environment causing environment variables to be propagated to
subprocesses, despite the protections supposedly offered by taint
checking.
With this update Perl changes the behavior to match the following:
a) %ENV is populated with the first environment variable, as getenv
would return.
b) Duplicate environment entries are removed.

Beginning in PathTools 3.47 and/or perl 5.20.0, the File::Spec::canonpath()
routine returned untained strings even if passed tainted input. This defect
undermines the guarantee of taint propagation, which is sometimes used to
ensure that unvalidated user input does not reach sensitive code.
This defect was found and reported by David Golden of MongoDB, and a patch
was provided by Tony Cook.

Configuration scripts expect the libc identifier to be "uclibc" in case we're using it,
OpenWrt provides "uClibc". Oh well...

This was previously manually set to '4.8.0'. Aside from just being incorrect,
it also breaks Errno's GCC5 detection.
Fixes#2044.

Despite being just a packaging update, this update packs quite a few changes.
To start things off, we're finally passing perl's testsuite on at least
x86/musl. There are a lot of skipped tests left, as well as some oddities.
Nothing too heavy though. Making this happen was an ongoing effort since the
perl-5.20.1 release.
We still can't run module testsuites and I don't expect all target/libc
combinations to pass yet. So we'll leave test suite support marked as
experimental.
We've also switched from the old collection of target-specific configuration
files to a new, more flexible and easier-to-maintain system based on
perlconfig.pl. It'll generate a suitable configuration file using information
found in it's *.config files as well as command-line parameters passed.
See the POD and files/README.config for details.

This replaces the previously used collection of configuration files for every single
architecture in conjunction with hacky overrides, which became an increasing burden to maintain.
Fixes a number of outstanding bugs and oddities, with the most important one being the
previously wrong signal order(as shown by ext/POSIX/t/sigaction.t).
See files/perlconfig.pl's POD and files/README.config for details.

- Add patch to inhibit the libm IEEE math switch on musl
- Add postprocessing for config.sh to the Makefile to fixup
defines for musl, idea taken
from http://patchwork.openembedded.org/patch/91707/
This is the least invasive approach I could come up to fix the build
failure asap. Another possibility is maintaining yet another set of
musl specific architecture config files, but I think that this introduces
a lot of maintenance overhead.

While host-perl only exists to run build scripts(and thus, should have
no influence on built packages at all), most packages depend heavily on the
feature set of the perl installation that ran their configuration scripts.
This change makes them see that threading support is enabled(if it actually
is selected).
We can't use configuration symbol overrides for this one, as they are
visible to host-perl as well. Using overrides would make it act as if it
had threading support enabled without actually having it.

- Formatting changes

-g3 will make the build fail in Compress-Raw-Zlib with
ld: final link failed: Memory exhausted
This bug is actually documented[1] and fixed by filtering that flag. Since
we're passing CFLAGS manually, we need to do the same to make things work.
I suspect that this is actually a linker or library bug, but for now let's
just replicate the official fix.

This is a kind of big commit. Summary:
- Integrate better into OpenWRT's infrastructure
- > Build host-perl using host-build.mk
- > Install host-perl to STAGING_DIR_HOST
- Remove microperl(for now)
