linking against libbfd without modify LD_LIBRARY_PATH

[Baojun Wang]

Many thanks for your help Mike.
The distro is gentoo (~amd64, up-to-dated) ;)

RPATH is /usr/lib64/binutils/x86_64-pc-linux-gnu/2.22

The problem is there is no such tool like pkg-config which can output
the lib path automatically, IE:

pkg-config --cflags --libs glib-2.0
-I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include  -lglib-2.0

Is it a known problem with Gentoo?

Best Regards
Baojun
