# The prevailing standard seems to be putting unstripped libraries in
# /usr/lib/debug/ and stripping the debugging symbols from all the other
# libraries.  Only linuxthreads versions are provided.

( cd $PKG/usr/lib/debug ; rm -f *_p.* )
# NOTE:  Is there really a reason for the glibc-debug package?
# If you're debugging glibc, you can also compile it, right?

## COMMENTED OUT:  There's no reason for profile libs to include -g information.
## Put back unstripped profiling libraries:
#mv $PKG/usr/lib/debug/*_p.a $PKG/usr/lib
# It might be best to put the unstripped and profiling libraries in glibc-debug and glibc-profile.

# I don't think "strip -g" causes the pthread problems.  It's --strip-unneeded that does.

## Install docs:

 cp -a BUGS C* F* I* L* N* P* R* V* W* $PKG/usr/doc/glibc-$VERSION
 find $PKG/usr/doc/glibc-$VERSION -type d | xargs chmod 755

if [ ! -r $PKG/usr/share/zoneinfo/localtime ]; then

fi

# But, it's hard to get me to break old habits, so we'll continue the tradition here:
chown -R root.bin $PKG/sbin $PKG/usr/bin $PKG/usr/sbin

# Strip most binaries:
( cd $PKG
 find . | xargs file | grep "executable" | grep ELF | cut -f 1 -d : | xargs strip --strip-unneeded 2> /dev/null
 find . | xargs file | grep "shared object" | grep ELF | cut -f 1 -d : | xargs strip -g 2> /dev/null
)

# Fix info dir:
rm $PKG/usr/info/dir
gzip -9 $PKG/usr/info/*

# This is junk
rm -rf $PKG/etc/ld.so.cache
rm -rf $PKG/sbin/sln
( cd $PKG
