support/libtool: improve version 1.5 static patching
Alter the libtool 1.5.x support patch to accomodate for wildly different
versions of ltmain.sh
Just make it alter incoming args from -static to -all-static which seems
to apply to all the different variants out there since argument parsing
is unlikely to change much.
