libtool, libglib2, *_HOOK_POST_(BUILD|INSTALL)

target: x86 uclibc/busybox

(1) libtool built by many packages use system paths to find shared- objects, producing libraries that don't work on target.

I'm using this shell script to patch libtool after configure:

#!/bin/sh
sed 's/sys_lib_search_path_spec=\"[^\"]*\"/sys_lib_search_path_spec=\" \"/' $1 >/tmp/sedtmp1
sed 's/sys_lib_dlsearch_path_spec=\"[^\"]*\" /sys_lib_dlsearch_path_spec=\"\"/' /tmp/sedtmp1 >/tmp/sedtmp2 #sed 's/shlibpath_var=LD_LIBRARY_PATH/shlibpath_var=\"\"/' /tmp/sedtmp2 >/tmp/sedtmp3
mv /tmp/sedtmp2 $1
chmod +x $1

(2) libglib2 builds some libs that use shared-objects from host system, even after patching its libtool.

eg gmodule/.libs/libgmodule-2.0.so.0.1504.0 << works
gmodule/.libs/libgmodule-2.0.so.0.1504.0T << host libs

Good one copied to staging, while the other goes to project_*, so binaries on the final image fail to run due to missing libs (eg instead of uclibc's libc.so.0, libgmodule requests libc.so.6 present in my Slackware host)

(3) How does one use {pkgname}_HOOK_POST_BUILD and INSTALL? I tried to use it on libglib2's mk but looks like it is ignored.

Thanks,
Fernando.
