Alexey Neyman a596ec5b39 Fix up the sysroot issue for sh4 in a different way
(see the comments in the code for details on the issue)

Old workaround in 100-gcc.sh stopped working (probably, due to one
of GCC version upgrades), so switch to the other approach originally
described there: adjust the list of multilibs to not include the
default target explicitly.
