[Bug 2137464] [NEW] crypto/ec/asm/ecp_nistp521-ppc64.pl output regex failure

[Ravi Kant Sharma]

Public bug reported:

I have a scenario where the ecp_nistp521-ppc64.pl matches the incorrect
param for output instead of crypto/ec/ecp_nistp521-ppc64.s

Here is the build log on Ubuntu 24.04.

It matches -fdebug-prefix-
map=/<<PKGBUILDDIR>>=/usr/src/openssl-3.0.13-0ubuntu3.7

This leads to ecp_nistp521-ppc64.pl writing output to STDOUT instead of
the file crypto/ec/ecp_nistp521-ppc64.s . The missing .s file leads
Missing .s file leads to gcc erroring out and build failure.

This does not happen on Questing and Resolute because the regex does not
match the openssl version release, it will fail once we have an SRU.
