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
