Building all of libapr natively and installing the extra binary is
wasteful when the binary is trivially compiled natively in the target
build.

Simply add a do_compile_prepend() that uses BUILD_CC and so on to
compile tools/gen_test_char.  As it only uses standard C headers this
is trivial and you won't need to patch the build at all (obviously
test when MACHINE is massively incompatible with the host, ie qemuarm
with x86 host).
