Bug description:
  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
  "linux64le" -I. -Iinclude -Iproviders/common/include
  -Iproviders/implementations/include -I.. -I../include
  -I../providers/common/include -I../providers/implementations/include
  -fPIC -pthread -m64 -Wa,--noexecstack -Wall -fzero-call-used-
  regs=used-gpr -DOPENSSL_TLS_SECURITY_LEVEL=2 -Wa,--noexecstack -g -O3
  -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -Wformat
  -Werror=format-security -fno-stack-clash-protection -fdebug-prefix-
  map=/<<PKGBUILDDIR>>=/usr/src/openssl-3.0.13-0ubuntu3.7
  -DOPENSSL_USE_NODELETE -DL_ENDIAN -DOPENSSL_PIC
  -DOPENSSLDIR="\"/usr/lib/ssl\"" -DENGINESDIR="\"/usr/lib/powerpc64le-
  linux-gnu/engines-3\"" -DMODULESDIR="\"/usr/lib/powerpc64le-linux-
  gnu/ossl-modules\"" -DOPENSSL_BUILDING_OPENSSL -DNDEBUG -Wdate-time
  -D_FORTIFY_SOURCE=3 -DAES_ASM -DECP_NISTP521_ASM -DECP_NISTZ256_ASM
  -DKECCAK1600_ASM -DOPENSSL_BN_ASM_MONT -DOPENSSL_CPUID_OBJ
  -DPOLY1305_ASM -DSHA1_ASM -DSHA256_ASM -DSHA512_ASM -DVPAES_ASM
  -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
  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.
