Bug#1010595: Please make xsimd available on all platforms

[Julien Lamy]

Hi again,
To sum up upstream's answer [1]: xsimd does not support a fallback 
mechanism anymore, and pythran should work fine without xsimd. On the 
ARM side, armel is not supported, as xsimd requires __ARM_ARCH >= 7 [2].

The only solution I see is to package xsimd 8.1.0 and restrict it to 
amd64, arm64, armhf and i386: this is what I just commited to salsa. Let 
me know if you have a better solution, otherwise I'll upload the version 
currently in salsa to unstable.
