[PATCH] configure: Add linux header compile support for LoongArch

Posted by Bibo Mao 10 months, 2 weeks ago

When compiling qemu with system KVM mode for LoongArch, header files in
directory linux-headers/asm-loongarch should be used firstly. Otherwise it
fails to find kvm.h on system with old glibc, since latest kernel header
files are not installed.

This patch adds linux_arch definition for LoongArch system so that header
files in directory linux-headers/asm-loongarch can be included.
