gcc: Configure all gccs with --disable-install-libiberty

OE uses libiberty from binutils, since its properly compiled as pic
archive and applications and other libraries needing libiberty can
properly link with it.

With this option applied, explicit delete of libiberty headers and
libraries is not required in install step, since they wont get installed
in first place.
