[PATCH 19.07 1/2] openssl: use --cross-compile-prefix in Configure

[Eneas U de Queiroz]

This sets the --cross-compile-prefix option when running Configure, so
that that it will not use the host gcc to figure out, among other
things, compiler defines.  It avoids errors, if the host 'gcc' is
handled by clang:

mips-openwrt-linux-musl-gcc: error: unrecognized command-line option
'-Qunused-arguments'

(cherry picked from commit 2f75348923e564f1b73fbc32f7cabc355cd6e2b9)
---

Besides the fix for clang, I'm cherry-picking this to sync 21.02 and
19.07 Makefiles.
