buildgcc: Apply patches with -p1

Turned out that there are versions of the patch command that use the
    left hand side path for new files created by a patch. This behavior is
    incompatible with some of our patches. Stripping the topmost dir from
    the path with -p1 helps.

While touching that line, I couldn't resist to drop a command
    substituion (the `echo $patch`). It really shouldn't be necessary as the
    path to the patch file is already expanded in the head of the for loop.
