Stefan Reinauer ccf28ba9cb Use -mno-sse to prevent overzealous gcc optimizations
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.

Stefan Reinauer 5e4e2290b6 Add -Werror to xcompile's testcc
If -Werror is not specified, tests for certain compiler flags
will emit a warning, which makes the build break since we compile
with -Werror.

Marc Jones 616da1ee7f Allow XGCCPATH to be set on the make command line.
The xgcc toolchain may be moved by the user and passed in on the commandline. Updates the Makefile and the xcompile script.

Stefan Reinauer 8d427ece81 Fix romstage creation with gcc 4.6 and CAR targets
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.

Stefan Reinauer 61aee5f4b1 In 2007 Adrian Reber suggested that we drop ASSEMBLY in favor of __ASSEMBLER__.
http://www.coreboot.org/pipermail/coreboot/2007-September/024665.html

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

Patrick Georgi patrick.georgi c5f773d7f4 Various changes to the buildsystem:
- 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

Patrick Georgi 26774f2b72 Make the kconfig-style build work in mingw:
* use relative paths in ldscript.ld and crt0_includes.h
* avoid use of dd(1) in xcompile
* build libregex for kconfig, if necessary
* work around missing utsname on win32
* unlink targets before rename on win32
* implement (crude) mkstemp for win32
* avoid open/read/close, use fopen/fread/fclose instead
* don't free certain data structures in romcc on win32 to
  avoid crashes (likely use-after-free())
* handle "\CRLF" and win32 style absolute paths (X:/ or X:\)
  in romcc
* make lzma (part of cbfstool) build on XP
* implement ntohl/htonl on win32
* handle CRLF in awk script
* set larger stack for romcc on win32
