This was triggered by gcc for some reason It included sys/types.h and
assumed sys/select.h to be there. And that seams to be the case in musl.

The problem with relibc here is that sys/types.h is are part of relibc
"include/*.h" files, while sys/select.h is generated by cbindgen. That
makes it impossible to #include select.h in types.h epsecially that
there are files like fcntl.c that uses types.h. They would complain
about missing headers. I fixed this by renaming sys/types.h to
sys/types_internal.h and then generating types.h using cbindgen as well
except for that. however fcntl and dlmalloc can include types_internal
instead of types.h

The problem here is that _Bool type is not defined in C++ yet this file
is using it. That leads to issues when compiling gcc. I borrowed the
same techniques used in other stdbool.h

FIX error: right operand of shift expression '(1 << BLA)' is greater than or equal to the precision BLA of the left operand [-fpermissive]

Normally one shouldn't be using this datatype ever, but then someone
have to tell that to gcc folks :(

This patch implements sys/user.h file that works for both x86_64 as well
as aarch64. This include file is used by sys/procfs.h which is needed
dependency for binutils. There is bug in this patch in aarch64 implementation
which is the lack of f128 implementation in rust, thus we can't create cbinding
for long double.

I faced many issues when compiling libstdC++-V3 and linking against
relibc mainly:
- Missing types (max_align_t)
- Different types definitions(ptrdiff_t , size_t)
- and the fact that wchar_t is part of standard C++ and it seams that we
  canno redefine standard types
