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 Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5224 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
