[Buildroot] [git commit branch/2020.11.x] package/libopenssl: fix issue when compiling with BR2_OPTIMIZE_G=y

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a8ee27108b6bc1a22e3060026af8ff6c7305bdfe
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.11.x

For instance on risc-v 64 arch the build would otherwise fail because
of undefined ucontext_t because "-DOPENSSL_NO_ASYNC" would not propagate
through to CFLAGS in the Makefile.
