For those wondering what happened with this:

binutils build with gcc with default PIE:

# grep Error binutils-git-89080.bfbf34d-1-x86_64-check.log
make[5]: *** [Makefile:7161: incremental_test_2] Error 1
make[5]: *** [Makefile:7185: incremental_test_5] Error 1

make[2]: *** [Makefile:1955: check] Error 2
make[1]: *** [Makefile:7547: check-ld] Error 2
make: *** [Makefile:2206: do-check] Error 2


binutils build with current gcc:

# grep Error binutils-git-89080.bfbf34d-1-x86_64-check.log
readelf: Error: the PHDR segment is not covered by a LOAD segment


I need time to fix this.  It is probably just test suite assumptions
rather than errors.
