From: William Roberts <william.c.roberts@xxxxxxxxx>
Add a linker script that exports only what was previosly exported by
libselinux.
This was checked by generating an old export map (from master):
nm --defined-only -g ./src/libselinux.so | cut -d' ' -f 3-3 | grep -v '^_' > old.map
Then creating a new one for this library after this patch is applied:
nm --defined-only -g ./src/libselinux.so | cut -d' ' -f 3-3 | grep -v '^_' > new.map
And diffing them:
diff old.map new.map
Fixes: #179
