Bug description:
  Up to now we have been building RISC-V packages for the RV64GC
  profile. With Ubuntu 25.10 we want to move to the RVA23U64 ISA
  extension profile.

  In scripts/Dpkg/Vendor/Ubuntu.pm we have to update CPPFLAGS, CFLAGS,
  OBJCFLAGS, CXXFLAGS, OBJCXXFLAGS and add a -march= value specifying
  the extensions.

  The mandatory RVA23U64 extensions are specified in
