Subject: [PATCH] src/modules/rlm_python: fix build with -Ofast

Stripping logic wrongly translates -Ofast into ast resulting in the
following build failure:

configure: /home/fabrice/buildroot/output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/bin/python3-config's cflags were "-I/home/fabrice/buildroot/output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/include/python3.11 -I/home/fabrice/buildroot/output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/include/python3.11  -Wsign-compare -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Ofast -g0 -D_FORTIFY_SOURCE=2 -DNDEBUG -g -fwrapv -O3 -Wall"
configure: Sanitized cflags were " -isystem/home/fabrice/buildroot/output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/include/python3.11 -isystem/home/fabrice/buildroot/output/host/powerpc64-buildroot-linux-gnu/sysroot/usr/include/python3.11   -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  ast  -D_FORTIFY_SOURCE=2 -fwrapv  "

[...]

powerpc64-buildroot-linux-gnu-gcc.br_real: error: ast: linker input file not found: No such file or directory
