Make sure it's your binary pulling in libgcc_s. I just went through a
few iterations of recompiling mplayer with different *FLAGS and each
time base gcc_s was pulled in. I then did an ldd -a `which mplayer` and
saw libschroedinger was the one actually pulling it in.

Recompiled libschroedinger with gcc46 by putting USE_GCC=46 in the
Makefile and sure enough:
% ldd `which mplayer`|grep gcc
        libgcc_s.so.1 => /usr/local/lib/gcc46/libgcc_s.so.1 (0x29625000)

In short, bsd.gcc.mk is doing the right thing, but dependencies may
screw things up.
