Subject: MFC r279980:

Allow relative pathnames in SRCS, so as to enable building software
which includes more than one file with the same name, in different
directories.

For example, setting:

SRCS+=	foo/foo.c bar/foo.c baz/foo.c

will now create separate objdirs 'foo', 'bar' and 'baz' for each of the
sources in the list, and use those objdirs for the corresponding object
files.
