Summary:                    Some portability fixes for running on a MacOSX host
Description: 
This patch addresses a few minor linuxisms or (non-BSD)isms in buildroot's
shell scripts.

1. Replaces "cp -a" with "cp -pPR". "-a" is just a conveinence for -pPR,
and none of the BSD-derived systems I've checked have it.

2. My 'sed' reqires an explicit empty string after -i, or else it will use
the "-e" arg as the extension for backups. Oops.

3. My 'sed' requires an EOL or semicolon before the closing curly in a
{foo...} construct.

4. Apple's GCC prints a version string that dependencies.sh can't handle.
This change removes any parenthesized bits from the version string before
looking for numbers, so it can handle version strings like
    powerpc-apple-darwin8-gcc-4.0.1 (GCC) 4.0.1 (Apple Computer, Inc.
build 5250)

1) I'd rather prefer if you could expand the host-sed check so we build a
working sed for your system.
2) That cp -a patch looks ok. For files, we usually (try to) use "cp
-dpf", so please use -dpf resp. -Rdpf
  Please attach a new split patch with just the cp changes.
3) I think that the current dependencies.sh should deal with this, please
verify.

Thanks in advance for attaching updated, separate patches that take the
comments above into account.
cheers,
Bernhard

To be flexible, i suggest we add
ifeq (linux)
CP_A:=cp -a
endif
ifeq (apple or bsd)
CP_A:=cp ...
endif

variants for "force" "recurse" should be provided.
