Ok,  I have never seen that and have built both with and without
-msingle-pic-base without any problems for a long time.  Disclaimer that
I haven't specifically tested it for quite a while either :-)

You cannot mix/match binaries though,  so either everything is built
without -msingle-pic-base,  or everything is built with
-msingle-pic-base,  no combinations of objects can work,

Cheers,
