perl: remove the double configure hack

configure had to be called twice because with --mode=cross the
miniperl-step failed.  However, just leaving out the --mode parameter
is sufficient to make it work.  Since GNU_TARGET_NAME is always
different from the host's tuple (it has -buildroot- in it), we can
safely assume that the configure script will automatically enter
cross mode.

Also fix a type in perladmin definition.
