[PATCH, WIP] gnu: libimagequant: Update to 2.12.6

Hello,

Just a simple update, but sadly, I am unable to build using QEMU for other platforms. Same as with previous version, it does NOT build correctly on armhf.

starting phase `configure'

source directory: "/tmp/guix-build-libimagequant-2.12.6.drv-0/source" (relative from build: ".")

build directory: "/tmp/guix-build-libimagequant-2.12.6.drv-0/source"

configure flags: ("CONFIG_SHELL=/gnu/store/7zp9ifpgm3zj481nk6jg1im13g4mza2g-bash-minimal-5.0.16/bin/bash" "SHELL=/gnu/store/7zp9ifpgm3zj481nk6jg1im13g4mza2g-bash-minimal-5.0.16/bin/bash" "--prefix=/gnu/store/m65h6a45pz3wpraiid99hqq0rcbk5s9w-libimagequant-2.12.6" "--enable-fast-install" "--build=arm-unknown-linux-gnueabihf")

It appears to be an false assumption of SSE2 support where there is none? In addition, the same error happens when building this new version on aarch64, but not the previous one. The package definition for gemmlowp might have a clue as to what to do here.

Since QEMU is a machine emulator/virtualizer, I'm not sure how relevant this is, but my machine's CPU does not have SSE2 itself, AFAIK.

Hello,

You mean using "-s armhf-linux"?

I tried to build it using this command:

and I have a build trace similar to yours. The issue seems to be that

the configure script does not detect our intent to cross-compile,

because it uses "gcc" instead of "arm-linux-gnueabihf-gcc".

Also armhf and aarch64 don't have the SSE instruction code as part of

the architecture. lensfun in gnu/packages/photo.scm has an example of

disabling SSE on all platforms except for x64_64 and i686.
