[PATCH] testsuite: analyzer: Require lp64 target for coreutils-group_number.c

[Dimitar Dimitrov]

Test fails on 32-bit targets with:
  FAIL: c-c++-common/analyzer/coreutils-group_number.c (test for excess errors)
  .../gcc/testsuite/c-c++-common/analyzer/coreutils-group_number.c:13:21: 
warning: conversion from 'long long unsigned int' to 'size_t' {aka 'unsigned 
int'} changes value from '18446744073709551615' to '4294967295' [-Woverflow]

Instead of a risky modification to the test source, fix by simply
requiring lp64 effective target.

With the patch, 32-bit mode is marked as unsupported on x86_64-pc-linux-gnu:
  $ make check-gcc-c RUNTESTFLAGS="--target_board=unix/-m32 
analyzer.exp=coreutils-group_number.c"
  # of unsupported tests          1

64-bit mode still passes:
  $ make check-gcc-c RUNTESTFLAGS="--target_board=unix 
analyzer.exp=coreutils-group_number.c"
  # of expected passes            1

Ok for trunk?

gcc/testsuite/ChangeLog:

        * c-c++-common/analyzer/coreutils-group_number.c: Require
        effective target lp64.
