Repair cython_aliases ARB_LIBRARY

[mkoeppe]

It was moved from sage-env-config to sage-build-env-config. However it is used in cython_aliases, as reported in https://groups.google.com/d/msg/sage-devel/lMDRg3OJtl4/zU-AQNZwAQAJ, which user packages may be using.

But actually I think a better solution than cython_aliases needs to be found in the longer term. Installed .pxd headers should be made usable without a special environment.

Yeah, most of what cython_aliases does is run pkg-config for you. I think the standard cython build tools allow you to do that manually if you want, but what's missing is a way to easily get e.g. all of the flags that sage itself used. Probably sagelib needs a *.pc file at some point, and you could just gets the libs/include-dirs from that.

funny spacing:

+var('ARB_LIBRARY',                   'arb')

It aligns with lines above

align at least the line directly above it too, then.
