uClibc now provides fexecve(), so crun can build just fine with
uClibc. However, argp-standalone is needed, just like it was needed
for musl.

crun unconditionally uses fexecve since its addition in commit
530d6f661e and
https://github.com/containers/crun/commit/ce4dfbb97a8a05bef125030eaa6c46c07a5f9344:
resulting in the following uclibc build failure:
/tmp/instance-11/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arceb-snps-linux-uclibc/9.2.1/../../../../arceb-snps-linux-uclibc/bin/ld: src/libcrun/crun-cloned_binary.o: in function `ensure_cloned_binary':
cloned_binary.c:(.text+0x1006): undefined reference to `fexecve'
In 6e3f7fbc07 (package/runc: add upstream security fix for
CVE-2019-5736), we made runc unavailable for uclibc toolchains, and crun
uses fexecve for that same reason, to fix CVE-2019-5736.
So, also make crun unavailable for uclibc toolchains.
