Currently building full gdb for MIPS musl fails because it's trying to
include <sgidefs.h> which is provided by glibc and uClibc, but not by
musl.
However, the kernel headers provide <asm/sgidefs.h> which has the same
definitions, so we can use that one instead.
Backporting a patch that has been sent upstream. Taken from here:

This commit adds a small patch to gdb that fixes the build of gdbserver
on m68k/coldfire:
../nat/linux-ptrace.c: In function 'linux_fork_to_function':
../nat/linux-ptrace.c:282:19: warning: implicit declaration of function 'clone' [-Wimplicit-function-declaration]
child_pid = clone (function, child_stack + STACK_SIZE,
^
../nat/linux-ptrace.c:283:5: error: 'CLONE_VM' undeclared (first use in this function)
CLONE_VM | SIGCHLD, child_stack + STACK_SIZE * 2);
^
../nat/linux-ptrace.c:283:5: note: each undeclared identifier is reported only once for each function it appears in
Thanks to Waldemar for pointing out the patch fixing this issue.

This commit small patches to gdb that fix redefined structures build
problems that occur when building on PowerPC, PowerPC64, PowerPC64le and
SuperH with the musl C library.
The PowerPC(64)(le) patch was taken from the Yocto Project, the SuperH
patch was inspired from the PowerPC patch. The issue has also been
reported upstream to the musl developers:

In glibc 2.25, the proc_service.h header was copied from gdb to glibc.
However, in the process the 'const' was removed, which leads to build
failures with glibc >= 2.25.
gdb 7.12.1 already contains this patch. The patch for 7.11.1 comes
straight from upstream, the patch for 7.10.1 is backported by me.

This revert the commit [1] which break the simulator for aarch64.
Backport the upstream fix instead (from 7.12).

Following reports from me of build failures of the GDB simulator for the
Blackfin architecture, Waldemar cooked a
patch (0005-fix-sim-compile.patch) that removes the typedef of SIM_CPU,
because there was a redefinition of this typedef for Blackfin. This was
not causing an issue with recent compilers as redefining the same
typedef is valid with recent compilers, but was causing build failures
with gcc 4.4.x.
However, by removing the common definition of SIM_CPU, this patch broke
the build of the GDB simulator on other architectures, which did not had
an architecture-specific redefinition of SIM_CPU (unlike Blackfin).
The crux of the problem is in a commit from Mike Frysinger, that tries
to refactor the SIM_CPU definition into a common one. Except that it
leaves a redefinition of it for Blackfin. Removing this second
definition however doesn't easily work, due to include ordering
issues. The easiest solution is to simply revert the patch from Mike
Frysinger. This allows to fix the build for all architectures and all
compiler versions.

With this config you can bootup a Linux kernel
in GDB simulator and test Blackfin kernel and
userland.
