Please don't do that.
LTO can be driven using only env variable.
% CFLAGS="<clto_cflags>" LDFLAGS="<lto_ldflags>" ./configure
Please use KISS principle and do not implement something which can be already
done other way *without* touching existing code.
PS. Changing {C,LD}FLAGS is not only part of using LTO. You need to pass NM,
RANLIB and AR env variables.
