gdb: Move defs.h before any system header in debuginfod-support.c
Commit Message
* defs.h includes config.h
* config.h may define _GNU_SOURCE
* if _GNU_SOURCE is defined, that must be before including any system
header (see feature_test_macro(7))
This is necessary to ensure that a prototype for mkostemp() is brought
into scope by <stdlib.h> when compiling filestuff.h, on platforms where
_GNU_SOURCE isn't unconditionally defined for C++ (i.e. not Linux).
In file included from ../../gdb/../gdbsupport/scoped_fd.h:24,
from ../../gdb/debuginfod-support.c:22:
../../gdb/../gdbsupport/filestuff.h: In function ‘int gdb_mkostemp_cloexec(char*, int)’:
../../gdb/../gdbsupport/filestuff.h:59:10: error: ‘mkostemp’ was not declared in this scope; did you mean ‘mkstemp’?
