musl: Fix CVE-2019-14697
musl libc through 1.1.23 has an x87 floating-point stack adjustment
imbalance, related to the math/i386/ directory. In some cases, use of
this library could introduce out-of-bounds writes that are not present
in an application's source code.
This problem only affects x86 and no other architectures.
