[OE-core] [PATCH 2/2] autotools.bbclass: use relative path to run configure script

[Robert Yang]

The absolute path (/path/to/configure) caused VPATH in Makefile to be an
absolute path, and then it will be in elf files, use relative path to
run configure can fix the problem.

This will reduce a lot of buildpaths QA issues in a world buld.
