[PATCH] crosstool + linux-libc-headers (was Re: problem with compiling for sh3eb)

Oh, ok. Did not know all.sh attempted a kernel build - all.sh never got 
further than "Please set /proc/sys/net/ipv4/tcp_tw_recycle to 1", and I 
never bothered to do so :)

Ok, so I will assume the following:

- all.sh will abort when either one is missing
How about when all.sh is called with the --notest option? If L*SANITIZED*DIR 
is set, we might require LINUX_DIR for testing purposes only, thereby 
avoiding the need to download another 30MB if the user is not interested in 
the test. (However, chances are about 99% the user will want the kernel 
sources anyway)

- crosstool.sh will still accept either one and use the sanitized headers if 
both are supplied
Since crosstool.sh only needs one of the two for the build, there is no use 
in requiring both.

- getandpatch.sh will just download whatever environment variables are 
provided
Since getandpatch.sh is either called by all.sh or by a user that knows what 
he is doing, I think there is little harm in leaving out sanity checks here.


Thoughts, anyone?
