make only needs to read Makefile.incs once, thanks to the
SECONDEXPANSION feature of GNU make (and we rely on GNU make for lots of things already) File paths are relative to the root directory, which simplifies debugging (make V=1 gives shorter command lines) and helps ccache finding matches for checkouts in different directories (even though it should normalize paths itself) Signed-off-by: Patrick Georgi <patrick.georgi@coresystems.de> Acked-by: Ronald G. Minnich <rminnich@gmail.com> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5304 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
