elfutils: fix gcc 8.0+ multistatement macros warning/error
GCC 8.0+ <https://gcc.gnu.org/gcc-8/changes.html> introduces a new
warning about unsafe macros expanding to multiple statements used
as a body of a statement such as if, else, while, switch, or for.
In combination with -Werror this can cause the compilation to fail:
|In file included from xmalloc.c:37:
|xmalloc.c: In function 'xmalloc':
|system.h:39:2: error: macro expands to multiple statements [-Werror=multistatement-macros]
| fflush(stdout); \
| ^~~~~~
|xmalloc.c:52:5: note: in expansion of macro 'error'
| error (EXIT_FAILURE, 0, _("memory exhausted"));
| ^~~~~
|xmalloc.c:51:3: note: some parts of macro expansion are not guarded by this 'if' clause
| if (p == NULL)
| ^~
