Maybe.  However, in the snipped out part of the log, gtkmain was
compiled to .libs/gtkmain.lo -- and that is the PIC version.  That
compiled fine.  Now, the build probably had both --enable-static and
--enable-shared.  So, libtool also builds a gtkmain.o non-PIC.  The
build is breaking there.  In the "both static and shared" mode,
'libtool' silences the compiler output for the non-PIC part, to cut
down on duplicate messages from the compiler.  However, in the case of
a crash in the non-PIC part, we don't have any compiler output to look
at.  We can get an explicit non-PIC build with unsilenced compiler
output by running

        make gtkmain.o
