Use a non-empty test program to test ability to link.
On bare-metal targets, I/O support is typically provided by a BSP and requires a linker script and/or hosting library to be specified on the linker command line. Linking an empty program with the default linker script may succeed, however, which confuses libstdc++ configuration when programs that probe for the presence of various I/O features fail with link errors. 2020-02-12 Sandra Loosemore <sandra@codesourcery.com> PR libstdc++/79193 PR libstdc++/88999 config/ * no-executables.m4: Use a non-empty program to test for linker support. libgcc/ * configure: Regenerated. libgfortran/ * configure: Regenerated. libiberty/ * configure: Regenerated. libitm/ * configure: Regenerated. libobjc/ * configure: Regenerated. libquadmath/ * configure: Regenerated. libssp/ * configure: Regenerated. libstdc++v-3/ * configure: Regenerated.
