+Subject: [PATCH] aclocal.m4: allow arbitrary <vendor> string in toolchain
+ triplets
+
+Canonical triplets have a form of
+    <arch>-<vendor>-<os>[-<abi>]
+
+Checking for vendor is almost never correct as it's an
+arbitrary string.
+
+It's useful to have multiple "vendors" to denote
+otherwise the same (WRT <arch>, <os>, <abi>) target:
+    --target=x86_64-pc-linux-gnu
+    --target=x86_64-unknown-linux-gnu
+    --target=x86_64-ghc80-linux-gnu
+    --target=x86_64-ghchead-linux-gnu
+
+Do not fail unknown vendors. Only emit a warning.
+Ideally configure checks should never use "vendor".
