--- Comment #1 from Yann E. MORIN <yann.morin.1998@free.fr> ---
stsp, All,

> buildroot seems to have some pkg-config wrapper that adds the sysroot path per every variable expansion.

Yes and no. Basically, that's pkconf (the pkg-config implementation Buildroot
is using) thatadds the sysroot prefix to all variable expansions. The wrapper
probided by Buildroot just ensure that the proper sysroot is used.

> I have a .pc file that emits -rpath on --libs. rpath with the sysroot prefix doesn't work.

Adding an -rpath link option should not be done in a .pc file; that's rather
incorrect.

Furthermore, the RPATH is fixed before assembling the filesystem images,
so that only RPATH valid on the targt are present (usually, none is needed);
see Makefile line 768.
