buildgcc: Add option to bootstrap a host gcc
Bootstrapping gcc is the recommended way if your host gcc's version
doesn't match the gcc version you're going to build. While a build
with an outdated host gcc usually succeeds, an outdated gnat seems
to be a bigger issue.
v3: Some library controversy: gcc likes the libraries it ships with
most but we don't want to install shared libraries. So we build
them static --disable-shared) and install only the minimum
(libgcc, libada, libstdc++). However, as the code of these
libraries might be used to build a shared library we have to
compile them with `-fPIC`.
v4: o Updated getopt strings.
o The workaround for clang (-fbracket-depth=1024) isn't needed
for bootstrapping and also breaks the build, as clang is only
used for the first stage in that case and gcc doesn't know
that option.
So far build tested with `make BUILDGCC_OPTIONS="-b -l c,ada"` on
o Ubuntu 14.04 "Trusty Tahr" (i386)
o Debian 8 "Jessie" (x86_64) (building python (-S) works too)
o current Arch Linux (x86_64)
o FreeBSD 10.3 (x86_64) (with gcc-aux package)
and with clang host compiler, thus C only: `make BUILDGCC_OPTIONS="-b"`
on
o Debian 8 "Jessie" (x86_64)
o FreeBSD 10.3 (x86_64)
v5: Rebased after toolchain updates to GCC 5.3.0 etc.
Build tested with `make BUILDGCC_OPTIONS="-b -l c,ada"` on
o Debian 8 "Jessie" (x86_64)
