PKGBUILD rule for use of $CARCH gives too many false positives
Any string match to ppc/arm gives an warning even though it valid use such as:
-iwholename '*/linux-armv7' -o
-iwholename '*/linux-arm' -o
Or see the qemu
PKGBUILD
qemu-system-{aarch64,alpha,arm,avr,cris,hppa,loongarch64,m68k,microblaze,mips,nios2,or1k,ppc,riscv,rx,s390x,sh4,sparc,tricore,x86,xtensa}
Which gives tons of useless warnings.
