Thank you to commit the patch posted to the ML (your comit may be based
on http://www.kaffe.org/pipermail/kaffe/2006-October/104681.html).

But, as a matter of fact, this patch does not solve my problem for
making arm/linux/jit works again. Or even, v1.3 of 'md.c' (not
using ARM_NR_cacheflush) does not solve it.

Since Sascha's report indicates (even he does not explicitly say so)
he tried to make his effort based on 1.1.7, I will try to check
whether this slightly old version works or not. If it works as
he reported, I have to step forward to the CVS head.

Yes, I know that cache flushing will be merged into glibc some day,
and this is the way to go as like as what happened on m68k/netbsd
several years ago (see 'm68k/netbsd1/jit-md.h' v1.5 and v1.7).
