[svn-r11019] Purpose: Add detection

Description: pgcc version 6.0x have optimization (-O, -O2, or -O3) problem.
It caused multi driver test to fail.  The problem happened in a macro
definition.

Solution: Detect these versions and add option "-Mx,28,0x8" to the compiler
to avoid the problem if optimization is enable.

Platforms tested: mir and fuss - simple change.
