Fix gdbsupport build
I'm seeing this on F27 (a clean build from scratch):
~~~~~~~~~~~~~~~~~~~~~~~~~~~
make[3]: Entering directory '/home/pedro/brno/pedro/gdb/binutils-gdb/build/gdbsupport'
CC gdb_tilde_expand.o
In file included from /home/pedro/gdb/binutils-gdb/src/gdbsupport/../gnulib/import/libc-config.h:33:0,

../bfd/config.h:7:4: error: #error config.h must be #included before system headers
# error config.h must be #included before system headers
^~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~
libc-config.h, where it includes config.h, says:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
/* This is intended to be a good-enough substitute for glibc system
macros like those defined in <sys/cdefs.h>, so that Gnulib code
shared with glibc can do this as the first #include:
#ifndef _LIBC
# include <libc-config.h>
#endif
When compiled as part of glibc this is a no-op; when compiled as
part of Gnulib this includes Gnulib's <config.h> and defines macros
that glibc library code would normally assume. */
#include <config.h>
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The issue is that that '#include <config.h>' picks up bfd's config.h
instead of gnulib's.
This problem doesn't trigger in the gdb dir because there we generate
config.h under that exact name so gnulib's libc-config.h ends up
picking gdb's config.h instead of gnulib.c and that ends up harmless.
In gdbsupport, the config.h file is really named support-config.h, so
that '#include <config.h>' in libc-config.h doesn't pick it like it
would if it had the conventional config.h name.
This patch fixes it by simply renaming gdbserver's support-config.h to
config.h.
gdbsupport/ChangeLog:
2020-01-17 Pedro Alves <palves@redhat.com>
* configure.ac: Generate config.h instead of support-config.h.
* common-defs.h: Include <gdbsupport/config.h> instead of
<gdbsupport/support-config.h>.
* Makefile.in: Regenerate.
* configure: Regenerate.
