cmd/cc: change getquoted() to accept whitespaces.
cmd/cc: change getquoted() to accept whitespaces.

getquoted() currently checks for whitespaces and returns nil
if it finds one. this prevents us from having go in a path
containing whitespaces, as the #pragma dynld directives are
processed through the said function.

this commit makes getquoted() accept whitespaces, and this is
also needed for solving issue #115.
