bpf: do not --enable-gcov for bpf-*-* targets
This patch changes the build machinery in order to disable the build of GCOV (both compiler and libgcc) in bpf-*-* targets. The reason for this change is that BPF is (currently) too restricted in order to support the coverage instrumentalization. Tested in bpf-unknown-none and x86_64-linux-gnu targets. 2022-02-23 Jose E. Marchesi <jose.marchesi@oracle.com> gcc/ChangeLog PR target/104656 * configure.ac: --disable-gcov if targetting bpf-*. * configure: Regenerate. libgcc/ChangeLog PR target/104656 * configure.ac: --disable-gcov if targetting bpf-*. * configure: Regenerate.
