[Ltib] Patch for building PCRE on systems with grep 2.7

[Mark]

Hello

The PCRE package fails to build on systems with grep 2.7 (or greater??). This 
is due to a grep update which now rejects regular expressions that use 
[:space:] instead of [[:space:]]. This affects 'configure' when it attempts to 
check for the correct version of ltmain.sh.

The attached patches are as follows:

pcre-6.3-grep.patch - changes the grep command in configure.
pcre-spec-grep.patch - updates the spec file to apply the above patch.

Didn't know whether to fix the '[:space:]' used by sed at the same time? Works 
okay at the moment, but I suppose that it could also change in the future.

Regards

Mark
