I have no particular objection to adding this (except a minor nit of
maybe the name should be ADDITIONAL_PLUGIN_TESTS). However the use of
this later is for the test:

  tests/tcg/x86_64/test-plugin-mem-access.c

and aside from the inline asm I don't see why this couldn't be a
multi-arch test. Could we not use the atomic primitives to make it multiarch?
