[OE-core] [PATCH 1/2] diffutils: do_configure: fix "Argument list too long"

[Robert Yang]

Fixed when len(TMPDIR) =  410:
aclocal: error: cannot open echo [snip]: Argument list too long

This is becuase it has a lot of m4 files, use relative path for them
can fix the problem.

It doesn't happen when MACHINE="qemux86", I think it is because
intel-x86-64 is longer than qemux86.
