gcc: Add 12.1

Add GCC 12.1 https://gcc.gnu.org/gcc-12/

The following patches from GCC 11.3.0 are no longer needed:
- 0005-arc-Update-ZOL-pattern.patch
- 0006-arc-Update-u-maddhisi4-patterns.patch
- 0007-arc-Fix-maddhisi-patterns.patch
- 0008-Darwin-aarch64-Initial-support-for-the-self-host-dri.patch
- 0009-libstdc-Check-for-TLS-support-on-mingw-cross-compile.patch

One new patch is needed to avoid issues building sh-unknown-elf:
- 0006-sh-Avoid-mb-m1-multilib-combination.patch

It is also necessary to build all-build-libcpp. This target exists as
far back as GCC 6 so has been done unconditionally.

+From: Keith Packard <keithp@keithp.com>
+Date: Sun, 24 Jan 2021 14:20:33 -0800
+Subject: [PATCH] Remove use of include_next from c++ headers
+
+Using include_next bypasses the default header search path and lets
+files later in the include path take priority over earlier files.
+
+This makes replacing libc impossible as the default libc headers will
+occur after the libstdc++ headers, and so be picked up in place of
+headers inserted at the begining of the search path or appended to the
+end of the search path.
+
+Using include_next is a hack to work-around broken combinations of
+libraries, and is not necessary in a well constructed toolchain.

+As a workaround add mb/m1 to the list of excluded combinations.
