Change additions from r50178 from if expr "$GCC_OPTION" to if expr
"X$GCC_OPTION" so expr doesn't get confused by the GCC_OPTION that
starts with a hyphen and spit out messages like this (on FreeBSD):

illegal option -- f
expr: usage: expr [-e] expression
expr: illegal option -- f
expr: usage: expr [-e] expression
no
