bug#24832: Hydra generates faulty derivation for gettext-boot0 on MIPS

[Mark H Weaver]

Almost all of the derivations being generated on Hydra for MIPS on the
'core-updates' branch differ from what is generated locally by guix on a
mips64el-linux machine.  The differences go at least as far back as
'gettext-boot0', where Hydra generates:

  /gnu/store/yzsx42kva1pgj96n9yir7j6xx0ndp7is-gettext-boot0-0.19.8.1.drv

but 'guix' on both my Yeeloong and on hydra-slave0 generates:

  /gnu/store/2zzkamx4a0wrv2372pxjm5kdd0jvnl76-gettext-boot0-0.19.8.1.drv

Comparing those two derivations, I see that the derivation built by
Hydra includes as an input:

  
/gnu/store/armz91zr59wzv0v0p3x9kvjxwzi714dx-ld-wrapper-x86_64-guix-linux-gnu-0.drv

but the one generated by 'guix' on a mips machine includes:

  
/gnu/store/cc5bm6lhpv6bfny24akih86jsgzx8j82-ld-wrapper-mips64el-guix-linux-gnu-0.drv

I guess this means that the entire 'core-updates' branch will need to be
rebuilt from scratch for MIPS :-(
