Build depends refer to source package names, not binary package names.

In many cases, PKG_BUILD_DEPENDS simply duplicated runtime dependencies of
a source package's binary packages; as the corresponding source packages
are implicitly added as bulid dependencies, PKG_BUILD_DEPENDS can simply be
dropped in these cases. In the other cases, *_BUILD_DEPENDS is fixed to
refer to the correct source package name.

Dependency of mysql-server is adjusted from libncursesw to libncurses
(as libncursesw is a virtual package provided by libncurses), so the build
dependency on ncurses is emitted unconditionally.

fix Makefile chmod (644)
replace MD5SUM with HASH
add PKG_MIRROR_HASH when PKG_SOURCE_PROTO:=git

(PKG_SOURCE_PROTO:=svn tarballs are not reproducible for now)

I admit this may be be a bit aggressive, but the lang
folder is getting cluttered/filled up with Python, PHP, Perl,
Ruby, etc. packages.

Makes sense to try to group them into per-lang folders.

I took the Pythons.
