[arm-gnu] Sourcery G++ Lite 2011.03-46 ARM uClinux is missing fork on all target arch. variants

["Rajeev V. Pillai" <rajeevvp@xxxxxxxxx>]

The Sourcery G++ Lite 2011.03-46 ARM uClinux library does not have the fork
syscall
implementation on _any of the target arch. variants_. This makes the
toolchain pretty useless
for non-trivial Unix programming.

Please implement a target architecture variant which has HW floating point
and enable syscalls
that depend on this, like fork, msync, mlock, munlock, etc.

Thanks.
