Bug#807420: lwjgl: FTBFS on ppc64el: error: wrong type argument to unary exclamation mark

[Fernando Seiti Furusato]

Source: lwjgl
Version: 2.7.1+dfsg-4
Severity: normal
Tags: patch

Dear Maintainer,

I am aware that this package has a newer version available.
But since it is in the repository, it would be good to have it building on
ppc64el as well.

The reason for the failure is because altivec is enabled by default on
ppc64el so all gets compiled with flag -maltivec on.
Consequently, macros definitions from altivec.h such as bool, vector and 
pixel get replaced along the code.

I included -mcpu-powerpc if the arch is ppc64le, but I am not sure this is
the best way to do so.

I know it works, because I tested on x86_64 and ppc64el.

Regards.

Fernando
