I already see lines like 

make[3]: Entering directory `/home/iant/gcc/bootstrap/x86_64-unknown-linux-gnu/libgcc'

That seems sufficient to me.

Top level Makefile.tpl.  As the comment at the top of that file
indicates, you generate Makefile.in from Makefile.tpl and Makefile.def
using autogen.

If bootstrapping:
    make BOOT_CFLAGS="-O2"
If not bootstrapping (i.e., building a cross-compiler):
    make CFLAGS="-O2"
