--- Comment #1 from Iain Sandoe <iains at gcc dot gnu.org> ---
I'm trying to reproduce this, (and could be making some mistake) but I seem to
see
checking dynamic linker characteristics... no
checking how to hardcode library paths into programs... immediate
checking for shl_load... configure: error: Link tests are not allowed after
GCC_NO_EXECUTABLES.
make[1]: *** [Makefile:13636: configure-target-libstdc++-v3] Error 1
at r14-4820-g11f50716eee812 (which is before the patches I applied at the
weekend)
What was the last revision that you know was working?

I confirm that build works fine with r14-4820-g11f50716eee812, no maintainer
mode, for pru and arm targets.
I'm using x86_64-pc-linux-gnu build and host machine.

If I remove the "AC_CHECK_LIBM" line from libquadmath/configure.ac, and
re-generate autoconf there, then the build passes.
I don't understand why that line was added. Just a few lines below I see checks
for specific functions from libm.

That was what I was expecting - that line should not be there (it is a rebase
glitch that did not get picked up in either reviews or testing)
I am just trying to reproduce the problem and that fix..
