Well, so why does
make -k check-gcc RUNTESTFLAGS='--target_board=unix\{-m32,-m32/-fpic,-m64,-m64/-fpic\} i386.exp=fentry*.c'
fail for -m32/-fpic then on x86_64-linux (current trunk)?

/usr/src/gcc/gcc/testsuite/gcc.target/i386/fentry-override.c:1:0: sorry, unimplemented: -mfentry isn't supported for 32-bit in combination with -fpic
/usr/src/gcc/gcc/testsuite/gcc.target/i386/fentry.c:1:0: sorry, unimplemented: -mfentry isn't supported for 32-bit in combination with -fpic
