This patch implements a relatively simple hash-based verification scheme
for downloaded files (tarballs):
After buildgcc downloads a file or notices that it has already been
downloaded, it hashes the file, and compares the hash against the known
hash stored in util/crossgcc/sum/$filename.cksum. Two errors can occur:
1. The hash file is missing. In this case, crossgcc asks the user to
verify the authenticity of the downloaded file. It also calculates
its hash and stores it in util/crossgcc/sum/$filename.cksum.calc.
If the file is authentic, the user may rename the calculated hash
file to $filename.cksum, so that it can be found the next time
buildgcc is started.
2. The known hash and the calculated hash differ. This is the case that
this patch seeks to protect against, because it may imply that the
downloaded file was unexpectedly changed, either in transit
(Man-in-the-Middle attack) or on the file server that it was
downloaded from. If buildgcc detects such a hash mismatch, it asks
the user to delete the downloaded file and retry, because it can also
be caused by a benign network error. If, however, the error persists,
buildgcc can't continue without risking that the user runs malicious
code, and it stops.
Note: The hash algorithm may be changed in the future, but for now I
left it at SHA-1, to avoid bloating this patch.

This patch has been provided by Mentor Chih-Chyang Chang
on behalf of Andes Technology. It fixes using the coreboot
toolchain to compile the Chrome EC code base on the ITE8320
embedded controller.
The new patch incorporates a fix for the issue previously
fixed by patches/gcc-6.3.0_nds32.patch, so that patch can
be removed.
patches/gcc-6.3.0_riscv.patch needs to be slightly adjusted
to still apply cleanly (configure scripts only).

Don't ask for bootstrapping in case of a different host GCC major
version. GCC's versioning scheme changed starting with the release
of GCC 5. There are no big changes between the versions any more.
Instead, show the message when the host GCC's version is below 4.
In case GNAT can't be found, ask the user to abort and install it.
Also give hints for Ubuntu where the package versions are a little
messy (e.g. the meta packages gcc and gnat often point to different
versions).
In case GNAT is found but is too old (< 4.9), enable bootstrapping
by default and tell the user that building will take longer.
In all three cases show a timeout to draw the user's attention.
v2: Update GNAT check to also look for `gnatbind`. It has to be
somewhere in $PATH.

When no CFLAGS are explicitly provided to it, the GMP configure script
will figure out the best optimization flags to use on its own. In
particular, it will setup the march, mfpu and mtune flags based on
hardware detection.
However, when CFLAGS are provided, they are used as-is and such
detection doesn't happen. When the march, mfpu and mtune flags are not
provided (which happens when GMP wasn't built already), not only will
related optimizations be disabled, but some code might not build because
of missing support. This happens with NEON instructions on ARMv7 hosts.
Thus, it is better not to set CFLAGS and leave it up to the GMP
configure script to get them right and still reuse those later.
