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

[Ravi Kant Sharma]

** Description changed:

  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.
  
  CC="gcc" /usr/bin/perl ../crypto/ec/asm/ecp_nistp521-ppc64.pl

  -DX25519_ASM  crypto/ec/ecp_nistp521-ppc64.s
  
  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.
+ the file crypto/ec/ecp_nistp521-ppc64.s . The 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.
