Hi Peter,

this CFLAG is needed for musl as well:
https://wiki.musl-libc.org/open-issues.html
"Legacy functions operating on ucontext_t (getcontext, setcontext, 
makecontext, swapcontext) are not implemented."

Otherwise the build fails:

./libcrypto.so: undefined reference to `getcontext'
./libcrypto.so: undefined reference to `setcontext'
./libcrypto.so: undefined reference to `makecontext'

Regards, Bernd
