It is no longer possible to switch to lang/gcc34 on Solaris (and maybe other 
platforms). Compilation in net/fetch fails with

cc: Warning: illegal option -nostdlib

ld: fatal: library -lgcc: not found
ld: fatal: File processing errors. No output written to fetch

The compiler flags (especially "-lgcc -lc -lgcc") are taken from bsd.prog.mk in 
pkgtools/bootstrap-mk-files.

NB that this error does not happen with lang/gcc46. But given the current state 
of lang/gcc4*, lang/gcc34 should be supported for some time, if possible.
>How-To-Repeat:

>Fix:
Reverting back to version 1.47 of lang/gcc34/Makefile fixes this problem.
