Revert "eglibc: fix perl path in target scripts on fedora 17 alpha"

This reverts commit 7c95d554c431451f975e1e5d0336d1fb7d0ce7ae.

eglibc uses the PERL to execute things as well as encoding the path
in target scripts. We will therefore have to resort to sed on the scripts
at do_install time to fix the problems originally reported. This patch
causes various weird build failures and needs to be removed.
