gcc uses its --with-build-config=bootstrap-lto --enable-link-serialization=1
when building gcc with LTO is enabled and the latter option ensures through
Makefile dependencies that for the large link commands only one is done at a
time.
And, for the new builds I've disabled the building with LTO, i.e.
%if 0%{?fedora} >= 35 || 0%{?rhel} >= 9
%ifnarch %{arm}
--with-build-config=bootstrap-lto --enable-link-serialization=1 \
%endif
%endif
and so it should consume even less memory.
Also, even when watching the LTO build that took more than 6 days,
several times I saw it going into the %check phase with running just the
testsuite.
