The offending part that made coreboot crash with some toolchains
was that gcc emits SSE instructions but coreboot did not enable SSE at
that point.
Since the gain for coreboot using SSE instructions is not measurable,
let's not use SSE instructions rather than enabling SSE early on.
One rationale behind this is that other parts of coreboot, like the
SMM handler would need fixing because the XMM registers are not saved
on SMM entry. Thus keep it simple.

If -Werror is not specified, tests for certain compiler flags
will emit a warning, which makes the build break since we compile
with -Werror.

The xgcc toolchain may be moved by the user and passed in on the commandline. Updates the Makefile and the xcompile script.

newer gcc versions generate ".section .text" instead of just ".text"
in their assembler output. This patch makes sure that we don't end up
with a superfluous ".section" that makes the build fail.
Add -Wno-unused-but-set-variable to CFLAGS if the flag exists.

It's about time we follow this advice.
Also move some manually set __PRE_RAM__ defines (ap_romstage.c) to the Makefile and
drop unused CPP define

- Single instance of the CC build rule in Makefile, instantiated as
necessary
- Remove manual static.o and option_table.o rules, they're now covered
by those instances of the CC build rule
- Normalize object file paths, so it can be $(obj)/option_table.o
instead of $(obj)/arch/i386/../../option_table.o now
- Add -pipe to compiler flags. It might be detrimental on rare scenarios
(building with extremly high disk bandwidth, eg. RAM disk), but it
significantly helps on win32 (which seems to cache less aggressively
than most unix-alikes)
- Silence stderr on hostname and domainname invocations (cosmetic fix
for cygwin)
- Test for -Wa,--divide functionality of the target compiler (taken from
abuild). It might be possible to remove most patches in crossgcc with that.
- Report build of failover.inc and romstage.inc
