This patch is for PR 79193 and 88999, problems where libstdc++ is
mis-configuring itself when building for a bare-metal target because
it thinks it can link programs without pulling in the BSP that
provides low-level I/O support. (Specifically, this was observed on
nios2-elf with Newlib and GDB semihosting.) It'll build just fine if
it recognizes that it can only compile programs and not link them, but
it's confused because using an empty program to test for ability to
link succeeds.
Is this configure change OK, and suitable for stage 4?
BTW, I did run autoconf in every subdirectory that contains a
configure.ac, but it appears only libstc++-v3 actually uses this test;
all the other regenerated configure scripts were unchanged.
Thanks for making this work properly.
No objection from me, but I can't approve the top-level configury
change, and the whole "no executables" thing is a bit of a mystery to
me. Joseph is probably the right person to approve that, if no other
relevant maintainer responds.
