Ah, good point. Here's the updated patch.

Subject: [PATCH] Move gdb-dlfcn.[ch] to gdbsupport/
I need to use 'gdb_dlopen' inside 'gdbsupport/', but it's not yet
supported there. This commit moves 'gdb-dlfcn.[ch]' to 'gdbsupport/',
which makes it available also on gdbserver.
gdb/ChangeLog:
2019-08-21 Sergio Durigan Junior <sergiodj@redhat.com>
* configure.ac: Don't check for 'dlfcn.h' (moved to
gdbsupport/common.m4).
* Makefile.in (COMMON_SFILES): Move 'gdb-dlfcn.c' to
'gdbsupport/'.
(HFILES_NO_SRCDIR): Likewise, for 'gdb-dlfcn.h'.
* compile/compile-c-support.c: Include
'gdbsupport/gdb-dlfcn.h'.
* gdbsupport/common.m4: Check for 'dlfcn.h'.
* gdb-dlfcn.c: Move to...
* gdbsupport/gdb-dlfcn.c: ... here.
* gdb-dlfcn.h: Move to...
* gdbsupport/gdb-dlfcn.h: ... here.
gdb/gdbserver/ChangeLog:
2019-08-21 Sergio Durigan Junior <sergiodj@redhat.com>
* config.in: Regenerate.
* configure: Regenerate.
