Some perl packages are installing scripts in /usr/bin, with a shebang line so that kernel knows how to interpret them.

Sometimes, the installed shebang is including the perl version, such as:

    #!/usr/bin/perl5.18.2

I propose that we add a new post-processing step in rpm to strip such perl version from the shebang line, to get back to:

    #!/usr/bin/perl

This would prevent the rebuilding of perl modules shipping scripts with wrong shebangs when updating perl.

It could be as simple as:
for f in $(ls $buildroot/usr/bin/*); do
  perl -pi -E '$.==1 && s{^(#!/usr/bin/perl).*$}{$1}' $f
done

thanks.
