Probably.

Because xgcc checks your path earlier than configure, which only checks it
if it can't find it in one of the standard paths.  This makes some sense;
for configuration, we want to look at an assembler that everyone can see,
while it might also be convenient to be able to override the assembler used
by an already-built compiler.  However, I think that PATH is not the way to
do that.
