[PATCH 0/4] dietlibc compatibility

I've started statically-linking git binaries against dietlibc to avoid
having to recompile it for every machine/distro and chroot (lots!) I
would use it in.

For building git (on a Debian unstable system with dietlibc-dev),
I used the following make vars:

	CC=diet -v gcc
	NO_STRCASESTR=YesPlease
	NO_SETENV=YesPlease

The dietlibc setenv() doesn't seem very nice to **envp in git.c,
resulting in $PATH being clobbered when it runs execve().  This
caused tests to fail.  Fortunately, gitsetenv() saved the day.

The following patches fix other issues I had with dietlibc.
