%bcond_without annobin_plugin
# Allow the building of annobin without using annobin itself.
# This is because if we are bootstrapping a new build environment we can have
# a new version of gcc installed, but without a new of annobin installed.
# (i.e. we are building the new version of annobin to go with the new version
# of gcc).  If the *old* annobin plugin is used whilst building this new
# version, the old plugin will complain that version of gcc for which it
# was built is different from the version of gcc that is now being used, and
# then it will abort.
#
# The default is to use annobin.  cf BZ 1630550.

# [Stolen from gcc-python-plugin]
# GCC will only load plugins that were built against exactly that build of GCC
# We thus need to embed the exact GCC version as a requirement within the
# metadata.
#
# Define "gcc_vr", a variable to hold the VERSION-RELEASE string for the gcc
# we are being built against.
#
# Unfortunately, we can't simply run:
#   rpm -q --qf="%%{version}-%%{release}"
# to determine this, as there's no guarantee of a sane rpm database within
# the chroots created by our build system
#
# So we instead query the version from gcc's output.
#
# gcc.spec has:
#   Version: %%{gcc_version}
#   Release: %%{gcc_release}%%{?dist}
#   ...snip...
#   echo 'Red Hat %%{version}-%%{gcc_release}' > gcc/DEV-PHASE
#
