gcc_arch check logic
Hi Randy,
During the test on my machine with gcc-4.1.2, if -march=native is not
supported by host gcc, a non-zero value(256) returns, otherwise 0 returns.
[LOG]
status is 256
result is gcc_test.c:1: error: bad value (native) for -march= switch
gcc_test.c:1: error: bad value (native) for -mtune= switch
Please confirm if this is same as your result.
Best Regards,
Zhenhua

The gcc arch check result is incorrect when gcc version is older
than
4.5.
Sanity checker requests user to add "-march=native" into
BUILD_CFLAGS even if the flag is not supported by host gcc.
The status is 0 when -march=native is supported by host gcc, so set
result to True, otherwise set result to False.
