Here it the 2nd patch resent. Thanks.

This patch fixes the EABI version mismatch link error "built-in.o has
EABI version 0, but ... has EABI verion 4". The problem happens when
linking the child builtin.o's using arm-xscale-linux-gnueabi linker. The
cause is built-in.o created by $(AR) has an EABI verison 0, while the
non-empty built-in.o's have EABI version 4. Use $(CC) to create the
empty built-in.o fixes the problem.
