Bug#717276: perl: enable systemtap support via -Dusedtrace

[Eric Wong]

Source: perl
Severity: wishlist

I would like to use systemtap to trace Perl under Linux.
The existing dtrace support in Perl may be used for this.

Passing "-Dusedtrace" to Configure as documented in INSTALL
should enable tracing support.

A Build-Depends on systemtap-sdt-dev would be required under Linux

Thanks for maintaining these packages and your consideration!
