catch.hpp: restore PPC support

[barracuda156]

PPC define taken from earlier version of libosmium:

libosmium/test/catch/catch.hpp

Line 2128 in b293e96

#if defined(__ppc64__) || defined(__ppc__)

Second commit is non-functional: removal of few unneeded double spaces.

catch.hpp is included as is from its upstream source. It is not maintained here. Please solve this issue with upstream (https://github.com/catchorg/Catch2).

I have opened a PR there: catchorg/Catch2#2619
No idea how long it gonna take to merge it and then have it updated here after that.

It has been merged upstream, but note that Osmium still uses Catch v2, not the current v3, so unless somebody ports you change back to v2, this might not end up there. I am closing this issue here now because there is nothing to be done here. I'll update the enclosed Catch version before releasing a new Osmium version to whatever is current at that time (but still Catch v2), I can't do more at the moment.

Thank you. Do you suggest backporting with upstream to get it into catch2?
