[PATCH] bootstrap: handle perl-5.11's changed --version output

[Jim Meyering]

the version number from its new --version output.
To address that, I've changed bootstrap to special-case perl:

Subject: [PATCH] bootstrap: handle perl-5.11's changed --version output

* build-aux/bootstrap (get_version): Handle perl separately,
since perl-5.11's --version output is different.
