I fixed some more (even syntax errors) in the patch, can't attach it
right now since IZ is down, but here it is.
Will attach a new patch, which
- defaults to armv4t
- fixes syntax errors in the patch (test has no < and > but -lt and -gt,
-a test is broken (either && or -a without test, missing $ before build_cpu)
- remove the "x$something" nonsense for test which doesn't play well with
test and -lt/-gt
- you should not assume the build_cpu is stricly arm. on my debian sid on a
sheevaplug the triplet is armv5tel-unknown-linux-gnu when not specifying
arm-* manually on the configure line. There's a reason we have arm* in
configure.ins case statements :)
The original "patch" obviously wasn't tested at all...

René
