[Buildroot] [PATCH 1/2] toolchain: introduce BR2_TOOLCHAIN_HAS_GCC_BUG_111001

[Waldemar Brodkorb]

e2fsprogs package fails to build for the SH4 architecture due to a gcc
13.2.0 bug that leads to:
during RTL pass: sh_treg_combine2
rw_bitmaps.c: In function read_bitmaps_range_start:
internal compiler error: Aborted

Let's add gcc bug to avoid to deal with architectures in packages
when a gcc bug arises. Let's instead deal directly with gcc
bug number.

It's been reported upstream:
https://gcc.gnu.org/bugzilla//show_bug.cgi?id=111001

No need to backport as gcc 13.20 was introduced recently in
buildroot.
