Subject: [PATCH] erts: don't loop indefinitely on --enable-pgo

In https://bugs.gentoo.org/686786 gcc-9.1.0 exposed
a bug in erts/configure: if compiler does not support
PGO flags the configure process calls 'yes = yes'
(indefinite loop) instead of 'test yes = yes'.

The change does not fix gcc-9.1.0 PGO detection but
fixes ./configure termination.
