The error messages appear to refer to the '1 .get_pic.17', e.g.
.globl 1 .get_pic.l7; .hidden 1 .get_pic.l7;
which seems to come from
glibc-2.3.2/sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h
where it appears originally as
.globl __sparc.get_pic.l7; \
.hidden __sparc.get_pic.l7; \
Note that __sparc is a predefined symbol on Solaris and some other environments;
it's not surprising to see it predefined on Linux, too.
