Subject: [PATCH] minimal-bootstrap: trim configure flags and slim python

Adds --enable-checking=release and --disable-{libgomp,libquadmath,libitm,libvtv,libssp,libatomic,libstdcxx-pch,nls} to all GCCs (those runtime libs are unused by the stdenv); switches gcc-4.6{,cxx} to install-strip; adds --disable-nls to binutils and coreutils; adds --disable-test-modules --without-ensurepip --without-static-libpython to python.

Bootstrap self-size 1.45 GB -> 940 MB; gcc46-cxx -14%, glibc -10%, gcc-latest -6% wall on the heavy builds.

(make -j was tried on tcc-built derivations and broke them silently; NOTE comments left in the affected files so this isn't re-attempted.)
