suite

gcc6 --enable-default-pie causes hundreds of errors in test suite
When building GCC6 weekly snapshot 20160306 and adding the --enable-default-pie
to the configure script, hundreds of errors occur when running the test suite.
Platform is X86_64 on Intel Xeon D1540 "Broadwell"
Using glibc-2.23 with configure options:
--prefix=/usr \
--disable-profile \
--enable-kernel=2.6.32 \
--enable-obsolete-rpc \
--enable-lock-elision=yes \
--enable-stackguard-randomization \
--enable-bind-now
Using binutils-2_26-branch with configure options:
--prefix=/usr \
--enable-shared \
--disable-werror \
--disable-gdb \
--with-system-zlib
Using gcc-6-20160306 with configure options:
--prefix=/usr \
--enable-languages=c,c++ \
--disable-multilib \
--disable-bootstrap \
--with-system-zlib \
--disable-libmpx \
--disable-libstdcxx-pch \
--enable-default-pie \
--enable-checking=release
Attached is the test suite summary for gcc built with --enable-default-pie. The
build without --enable-default-pie but all other configuration options being
the same yielded only the 3 errors in PR ld/12365 of binutils 2.26 and these
are false positives. There were also 2 libstdc++ errors that are marked
"experimental" that occurred in both tests, so I am ignoring them.
