[PATCH] configure: Fix linux-user host detection for ppc64le

[Joel Stanley]

Revert the changes in the recent "Fix linux-user host detection for
riscv64" patch as it broke ppc64le. Instead add riscv to the switch
statement that performs normalisation of the host cpu name.

Fixes: 89e5b7935e92 ("configure: Fix linux-user host detection for riscv64")

Tested on a ppc64le host. Please check it works on riscv too.
