[PATCH] Disable all target libraries if not building gcc

[H.J. Lu]

I am working on SHF_COMPRESSED support:

http://www.sco.com/developers/gabi/latest/ch4.sheader.html

I will import zlib from GCC source tree into binutils-gdb tree.  But zlib
failed to build as a target library in binutils-gdb.  There is no need to
build target libraries if not building gcc.  OK for master?

Thanks.
