Subject: [PATCH] xargs: avoid sc_useless_cpp_parens failure

$ make syntax-check
...
xargs/xargs.c:674:#if !(defined(SIGUSR1) && defined(SIGUSR2))
maint.mk: found useless parentheses in cpp directive
make: *** [maint.mk:924: sc_useless_cpp_parens] Error 1

* xargs/xargs.c (main): Simplify -P #if conditional to avoid the
above syntax-check failure.
