[kaffe] Unused 'libgc' is always loaded.

[Kiyo Inaba]

Hi,

I noticed if I install 'libgc.so' in /usr/local/lib, the wrapper script
'kaffe-bin' always trys to load this library (even for 'kaffe-gc') and
if I did not set LD_LIBRARY_PATH to include /usr/local/lib, 'kaffe-bin'
generates error message saying

    kaffe/kaffe/.libs/lt-kaffe-bin: error while loading shared libraries: libgc.so.1: cannot open shared object file: No such file or directory

I think '-lgc' is only needed for 'boehm-gc' configuration.
