muslc needs va_copy fix and fails many test #522
Description
I compiled on Alpine Linux on amd_64
compilation fails, _va_copy is not available.
An easy fix has been commited in: https://github.com/gnustep/libs-base/tree/muslc
I am unsure if this fix is generic or not, _va_copy might be generally substituded with va_copy except on gcc 2.95 which we don't support anyway, but I only did a quick research online.
With the fix compile works, but I get a huge number of failures

Need to compare this with 32bit soon.
