Subject: [PATCH] media-libs/libjpeg-turbo: fix SIMD issues

This adds a NEON CPU flag to disable SIMD on ARM CPUs without NEON,
which avoids ABI-related build failures.

This also drops the obsolete x32 workaround, and it fixes assembler
package detection to use BROOT.

Closes: https://bugs.gentoo.org/792810
Package-Manager: Portage-3.0.18, Repoman-3.0.2
