Those return codes are only defined for the parisc architecture and
are leftovers from when we wanted to be HP-UX compatible.
They are not returned by any Linux kernel syscall but do trigger
problems with the glibc strerrorname_np() and strerror() functions as
reported in glibc issue #31080.
There is no need to keep them, so simply remove them.

parisc is the only Linux architecture which has defined a value for ENOTSUP.
All other architectures #define ENOTSUP as EOPNOTSUPP in their libc headers.
Having an own value for ENOTSUP which is different than EOPNOTSUPP often gives
problems with userspace programs which expect both to be the same. One such
example is a build error in the libuv package, as can be seen in
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900237.
Since we dropped HP-UX support, there is no real benefit in keeping an own
value for ENOTSUP. This patch drops the parisc value for ENOTSUP from the
kernel sources. glibc needs no patch, it reuses the exported headers.

For each arch in tools/perf/arch, grab a copy of errno.h.
This is a pre-req to generate an architecture specific mapping of errno
numbers to their names. This errno mapping can be used by perf trace to
support cross-architecture trace reports and to get rid of the
audit-libs dependency.
