After fixing the <bits/local_lim.h> issue by using <limits.h>, the
build still fail with udefined __WORDSIZE.
Adding <sys/user.h> to define __WORDSIZE reveal that xenomai use
<error.h> which is not provided by musl.
The discussion on the musl mailing list [1] about glibc error reporting
functions concluded to not add this support in the C library.
For now, disable Xenomai user space support for musl toolchains since
it require several patches to build correctly and needs to remove each
glibc error reporting functions.
Users interested in musl support for Xenomai can work with upstream to
fix these issues and revert this patch.
