Only link with libbsd when we are using GLIBC

Signed-off-by: Matthew McClintock <msm-oss@mcclintock.net>

Several problems were found with building against an external toolchain:

* TARGET_CPPFLAGS was missing which would prevent finding the headers
* TARGET_LDFLAGS also was not passed correctly
* when building against glibc, since we use strlcpy() we need to link
  against libbsd

Adds supports for hfsprogs, allowing the creation and verification of
HFS/HFS+ filesystems.

This creates two selectable packages:
- hfsfsck
- mkhfs

A filesystem checking script is included with hfsfsck to allow OpenWrt
to check/repair filesystem errors.

Using Ubuntu's 332.25 sources plus their patches from debian/patches/.
