tools.mk: support override CC/LD command line

due to Android NDK's clang is x86_64-linux-android28-clang --sysroot ${SYSROOT_PATH}
and it's ld is x86_64-linux-android-ld,
it's not able to use a single pattern to discript clang and ld.

and there is a error for x86_64-linux-android-ld.
x86_64-linux-android-ld  -L/home/ning/source/criu/protobuf-c/../target/lib -lprotobuf-c -r -z noexecstack -T ./compel/arch/x86/scripts/compel-pack.lds.S  -o criu/pie/parasite.built-in.o  criu/pie/parasite.o criu/pie/pie.lib.a ./compel/plugins/std.lib.a
./compel/compel-host hgen -f criu/pie/parasite.built-in.o -o criu/pie/parasite-blob.h
Error (compel/src/lib/handle-elf-host.c:335): Unexpected undefined symbol: `'. External symbol in PIE?
criu/pie/Makefile:49: recipe for target 'criu/pie/parasite-blob.h' failed

rebuild with host ld, can pass build.

so support override CC/LD from command line can pass build.
