install-tl-unx deps need to be rechecked on x86_64

[ken@…]

Last night, I had problems with asy on i686 and eventually realised it had unment dependencies. Today I've sorted out a script to list the deps and discovered asy is also using libGLU which these days is separate from Mesa.

I am 99% certain that I removed libGLU as a dep when upgrading to this year's install-tl-unx because it did not seem to be needed (on x86_64), but perhaps I made a mistake. I was also very surprised to find libreadline5 used by the i686 binary.

I'll be putting an x86_64 build onto this box sometime, I can check this then.

In fact, asy on 32-bit x86 needs fftw, libGLU, libreadline5 but does not need these on x86_64. Fixed at r14297.
