- Skip the libtoolize/autoreconf step in %prep on el6 only. pcre2 10.48 raised AC_PREREQ to 2.69 and el6 ships an older autoconf, so %prep died with "Autoconf version 2.69 or higher is required" before anything was compiled - which is why el6 was left on 10.34-2 while el7 and el8 moved to 10.48-1. Nothing we patch needs the build system regenerated: pcre2-10.10-Fix-multilib.patch only edits pcre2-config.in, which is in AC_CONFIG_FILES of the shipped configure and is expanded by config.status. Verified that the shipped ./configure alone, with the multilib patch applied, emits pcre2-config with empty libR and libS and no -L@libdir@. Every other platform keeps regenerating exactly as before.
