Subject[PATCH] scripts/gcc-goto.sh: Show stdout and stderr for potential errors
Date
From: He Zhe <zhe.he@windriver.com>

The check may fail not only because ${CC} does not support the asm
feature, but also due to potential defects of ${CC} itself like what
we experienced below or even it's missing.

Assembler messages:
Fatal error: The input and output files must be distinct
(introduced by binutils-2.31 "Stop the assembler from overwriting its
output file.")

This patch enables stdout and stderr to give user direct error
information for those cases, while not polluting the output for normal
cases.
