| +All of GDB's local Gnulib patches were already fixed upstream per their
| +descriptions, so this patch removes them all.
| +
| +The problem listed here:
| +https://sourceware.org/ml/gdb-patches/2019-08/msg00553.html
| +was probably partially fixed by moving gnulib to the toplevel;
| +however, to fix the remaining issues I had to add a local patch
| +to override $(CC) in import/Makefile.am. Here is the rationale:
| +
| +  The toplevel makefile overrides $(CC) (in EXTRA_HOST_FLAGS), which breaks
| +  in Gnulib with older GCCs, because it uses this variable to store the
| +  C11 flag (-std=gnu11). Override it here so we always get the value
| +  from configure.

PS5, Line 25:

In case somebody wants to reproduce the problem, it would be good to
mention that this happens with compilers that don't use c99 by
default, like gcc 4.8.5 on Centos 7.
