sevan cc576e1d8e Update supporting files for components which rely on autoconf to allow systems
introducing since release of software to be recognised. This should hopefully
allow the builds to progress a littles further on systems such as the POWER8
which features a little endian 64-bit PowerPC CPU identified as ppc64le.

lib:
	libasan is disabled currently (haven't tried yet)

new stuff:
	cc1objcplus
	collect2 -- need to re-introduce?
	libcilkrts
	libmpx
	liboffloadmic
	libvtv
	libitm

other changes to look at:

Index: gcc/targhooks.c
	vs new binutils

arch/feature list.  anything not here has been switched already:

tools:		does build.sh tools work?
kernels:	does a kernel run?
libgcc:		does libgcc build?
native-gcc:	does a full mknative-gcc complete?
make release:	does build.sh release complete? 
runs:		does the system boot with a full world?
atf:		does atf run / compare well

[2] - -O2 and -Os kernels hang, -O1 SIR reset
	-- may be a SMP issue; ultra10 works, ultra45 SMP does not
		-- try sb2000 (particularly with UP kernel.  u45 UP is shitty.)
[3] - MKCOMPAT=no enabled currently, infact OABI seems to be broken.  the docs say it was only deprecated, but the options make broken stuff.
[5] - sh3eb tries to use sh specific atomic config which doesn't work, has hand edited mknative output
[6] - crtbeginS.o builds incorrectly with GCC 5.3 and -O2.  a hack for -O1 has been added.
[8] - sgimips64 release build fails, mdsetimage'd gz'd kernels don't get built?
[10] - needs to be re-merged with GCC 5.3 versions of these not-merged-to-mainline-gcc ports.
[13] - builds tested:
       - m68k: mvm68k amiga atari
       - earm : shark evbarm*
       - mipseb: sgimips evbmips
       - mipsel: evbmips
       - mips64eb: sgimips[fail] evbmips
       - mips64el: evbmips
[14] - machines tested:
       - sparc ss20 (OK)
       - sparc64 ultra45 (FAIL), ultra10 (OK), sb2000 (OK UP, FAIL SMP.)
       - powerpc pegasosII (OK)
       - alpha UP1000 (OK)
       - arm shark (OK)
       - evbmips gxemul MALTA
		- had to implement some MIPS32 in gxemul to make this work
       - pmax gxemul (OK)
       - sgimips O2 (OK kernel -- but my O2 is not stable)
       - i386/amd64 (OK)
       - hppa (OK)
       - amiga (OK)
[15] - vax -- switched to GCC 5.3 already as it is less broken
	- ssh is broken, was broken with 4.8
	- there are too many -O0's we added because of mis-handled rtl
	- the eh_frame stuff is probably busted, but it never worked?
[16] - kernels tested:
	- m68k: amiga
