Quote from the original patch description:

[[[[
Build fix for MIPS with musl libc

The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
but not by musl. Regardless of the libc, the kernel headers provide
<asm/sgidefs.h> which provides the same definitions, so use that
instead.

Upstream-Status: Pending

Despite the "Upstream-Status" line, I wasn't able to find this issue in the
GDB's bugzilla - so submitting it.

This has been reported as an issue in crosstool-ng:
https://github.com/crosstool-ng/crosstool-ng/pull/517

The patch was originally provided for OpenEmbedded:

Hi. Thanks for the patch.

The gdb project doesn't generally review patches in bugzilla.
Instead please follow the contribution guidelines:

I did awhile ago, the patch was discussed and rejected: GDB developers point a
finger at musl, and musl blames gdb:

GDB developer's response:

MUSL developer's response:

Would be nice if GDB and MUSL guys could talk directly without me serving as a
middle man.
