gdb: update gnulib import
This is mostly to get this commit from gnulib:
e22cd2677a4b7beacbf30b93bb0559f7b89f96ce
Add ‘extern "C"’ to count-one-bits.h etc.
... which fixes this compilation problem I observed with clang++:
CXXLD gdb
arch/arm-get-next-pcs.o:arm-get-next-pcs.c:function thumb_get_next_pcs_raw(arm_get_next_pcs*): error: undefined reference to 'count_one_bits(unsigned int)'
<more such undefined references>
I built-tested on GNU/Linux x86-64 (gcc-9 and clang-9) as well as with the
x86_64-w64-mingw32-gcc cross-compiler.
gnulib/ChangeLog:
* update-gnulib.sh (GNULIB_COMMIT_SHA1): Bump to
e22cd2677a4b7beacbf30b93bb0559f7b89f96ce.
* Makefile.in, config.in, configure, import/*: Re-generate.
