The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.
This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.
Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

The '-e' option to echo and brace expansion are not guaranteed to be supported
by a POSIX-compliant /bin/sh (e.g. dash)

Greg Schafer <[email protected]> reported:
====
$make mrproper
scripts/gcc-version.sh: [[: command not found
This is on a very old host with an ancient bash as /bin/sh. But I have
CONFIG_SHELL set and pointing to a modern bash. Something is wrong.
This doesn't happen with 2.6.23

Fixed using a more common string equality test.

Currently, if you call scripts/gcc-version.sh without arguments it will
generate this output :
$ sh scripts/gcc-version.sh
scripts/gcc-version.sh: line 12: [: =: unary operator expected
scripts/gcc-version.sh: line 16: -E: command not found
scripts/gcc-version.sh: line 17: -E: command not found
0000
Not too pretty. I believe this is an improvement :
$ sh scripts/gcc-version.sh
Error: No compiler specified.
Usage:
scripts/gcc-version.sh <gcc-command>

Prints a six-digit string including the GCC patchlevel. Also fix
the 'usage' comment for cc-version.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
