I would like to use tasking support for GNAT on an arm-linux target (Intel
XSCale PXA 270) to the gcc-4_1-branch
The installed runtime library however is using generic dummy package for
tasking support (e.g. s-taprop.ads).
After having a look at gcc/ada/Makefile.in, I figured there needs to be a
couple of changes:
1. need for system-linux-arm.ads - which can be identical to
system-linux-x86.ads
2. The Makefile.in needs to be changed as follows:
(g-soccon is not in my focus, so I just kicked it out for now)
(a-numaux is using the libc bindings)
(all the rest of this section is from the x86-linux part)

Did I forget anything? Unfortunately, I don't have a running (native) compiler
(yet??), so ACATS tests might be hard to do.
