Revert "Update gnulib to current upstream master"

This reverts commit 7a6dbc2fdb2323c35e981f93236f323e9d7c0b24 ("Update
gnulib to current upstream master").  It is needed because the gnulib
update caused problems with people using old GCC compilers (version
4.8, for example), which support C99 but don't default to using it.
Unfortunately this broke GDB for these users.  A more detailed report
of what happened can be found at:

  https://lists.gnu.org/archive/html/bug-gnulib/2018-08/msg00157.html

The reason for updating our gnulib copy was to fix PR gdb/23558.
Reverting this patch reintroduces the bug, so in order to fix it I
will submit a subsequent patch which cherry-picks the fix from gnulib.
