libtool: patch the libtool script for native envs when cross

Browse source 
When libtool is cross compiled, it introduces assumptions about
the cross toolchain into the resulting /usr/bin/libtool script,
which prevents the script from working when used on the target
machine in a "native" environment.

The reason for this is primarily that the "short triplet" versions
of the binutils tools do not exist in the target system, only in
the crosstoolchain. Even if they did though, this would still be
wrong.

This impacts some real packages, for example libtommath does not
build when built natively in an environment for which libtool was
cross compiled.
