2012-01-17	Magnus Granberg		<zorry@gentoo.org>

		* Makefile.in	We add -fno-stack-protector to BOOT_CFLAGS, LIBCFLAGS and
			LIBCXXFLAGS if enable_esp yes.
		* gcc/Makefile.in	Add -fno-PIE. to ALL_CFLAGS and
			ALL_CXXFLAGS if enable_esp yes.
			Echo enable_esp and enable_crtbeginP to tmp-libgcc.mvars.
		* libgcc/Makefile.in	Add crtbeginP.o to EXTRA_PARTS if enable_crtbeginP yes
			We add new file crtbeginP.o if enable_crtbeginP yes
			Add -fno-PIE. to CRTSTUFF_CFLAGS.
