The following routines in libgcc on hppa are provided by glibc:
dave@mx3210:~/gnu/gcc/objdir/hppa-linux-gnu/libgcc$ nm libgcc_s.so.4|grep " U "
         U abort@GLIBC_2.2
         U calloc@GLIBC_2.2
         U _dl_find_object@GLIBC_2.35
         U free@GLIBC_2.2
         U malloc@GLIBC_2.2
         U memcpy@GLIBC_2.2
         U memmove@GLIBC_2.2
         U memset@GLIBC_2.2
         U pthread_cond_broadcast@GLIBC_2.3.2
         U pthread_cond_wait@GLIBC_2.3.2
         U pthread_getspecific@GLIBC_2.34
         U pthread_key_create@GLIBC_2.34
         U pthread_mutex_lock@GLIBC_2.2
         U pthread_mutex_unlock@GLIBC_2.2
         U pthread_once@GLIBC_2.34
         U pthread_setspecific@GLIBC_2.34
         U realloc@GLIBC_2.2
         U strlen@GLIBC_2.2

If any of these are implemented in qemu, they also may need the attribute fix.
