[gentoo-dev] [PATCH] toolchain-funcs.eclass: add detection for loongarch

[WANG Xuerui <i.gentoo@xen0n.name>]

From: WANG Xuerui <git@xen0n.name>

The Linux port currently under review has arch/loongarch, and should
almost certainly remain that way till merge; meanwhile it's ARCH=loong
on the Gentoo side, per mailing list discussion[1] and eselect
adaptation[2]. This architecture is little-endian-only according to the
manual[3].
