jump label: Fix GCC feature check when distcc is used

The following build bug occurs on distcc builds:

   CC      arch/x86/kernel/asm-offsets.s
 In file included from include/linux/module.h:24,
                  from include/linux/crypto.h:22,
                  from arch/x86/kernel/asm-offsets_64.c:9,
                  from arch/x86/kernel/asm-offsets.c:5:
 include/trace/events/module.h: In function 'trace_module_load':
 include/trace/events/module.h:18: error: expected '(' before 'goto'
 include/trace/events/module.h:18: error: expected identifier or '*' before '(' token

It triggers because distcc is invoked by turning $CC into "distcc gcc",
but gcc-goto.sh check script was using $1 not $@ to expand parameters.
