The failures happen on both Solaris/SPARC and x86, 32 and 64-bit. The error
is always of the same kind:
+FAIL: libphobos.druntime_shared/core/atomic.d (test for excess errors)

libphobos: Build all modules with -fversion=Shared when configured with
--enable-shared
which dropped -fno-moduleinfo in both
libphobos.druntime_shared/druntime_shared.exp and
libphobos.phobos_shared/phobos_shared.exp.
I've spot-checked that manually rebuilding a failing testcase with
-fno-moduleinfo added back both avoids the linker warning and lets the test
execute
successfully.
