Hi,

I was trying to cross build strace tip for ARC which was failing in weird ways -
running bootstrap cured it.

However in the process - when starring at config.log I see a lot config test
failures (even when configuring for host x86_64)

--------->8------
configure:7208: gcc -c -g -O2  conftest.c >&5
conftest.c: In function 'main':
conftest.c:66:21: error: expected expression before ')' token
 if (sizeof ((mode_t)))
                     ^
configure:7208: $? = 1
configure: failed program was:
--------->8------

It seems there is an extra set of parentheses which causes this.... I mean those
tests would pass otherwise
Is this expected, are others seeing this too....  Is this due to Ubuntu host 16.04

gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.2)
autoconf (GNU Autoconf) 2.69


TIA,
-Vineet
