gnustep-make-1.6.0

[Carl Eugen Hoyos]

I tested gnustep-make-1.6.0 on i86-linux,
mips-irix6.5, sparc-solaris2.7, ppc-darwin and i86-mingw.

To use statically linked tools on linux, the Linux ELF section of
target.make has to be changed from
STATIC_LDFLAGS += -static
to
STATIC_LDFLAGS +=

configure still doesn't test the right thread library for irix6.5: It has
to be -lpthread instead of -lthread.

Similar on darwin: Instead of -lthread, nothing has to be passed to the
compiler to test threads.

solaris & mingw seem to work well!
