libc++'s stddef.h uses non-standard macros to detect if max_align_t exists,

which break on musl. We reluctantly add musl's non-public macro the list
|

for now, but this should be fixed more fundamentally.

musl doesn't support the locale things that the locale requirements test, like
|
||||
localized money and decimal formatting.
|
||||
|
||||
The syscat.errcat tests are broken and rely on the libc to return a specific
|
||||
string in the form of "Unknown error <n>" for unknown errnos when calling
|
||||
strerror(), which is not defined anywhere and libcs are free to return any
|
||||
string they want, up to and including "libcxx tests are silly".
|
||||
|
||||
Similarly to glibc, musl uses "NaN" to format NaN long doubles, not "nan".
|
||||
Finally, musl uses "0" to indicate a NULL pointer as %p argument to *printf().

As per r241993, libunwind_ext.h is not used anymore, and thus only the public libunwind includes are needed.
|
||||
This eases distro packaging efforts and removes an unneeded requirement for out-of-tree building.
