I'm seeing that osdemo fails to build with undefined references (like
Brian reported):

  CC     osdemo.o
  CCLD   osdemo
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_add_symbol'
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_symbol_scope'
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_pop_scope'
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_find_symbol'
/usr/lib64/libglsl.so: undefined reference to `_mesa_new_shader'
/usr/lib64/libglsl.so: undefined reference to `_mesa_reference_shader'
/usr/lib64/libglsl.so: undefined reference to
`_mesa_symbol_table_add_global_symbol'
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_push_scope'
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_ctor'
/usr/lib64/libglsl.so: undefined reference to `_mesa_symbol_table_dtor'
collect2: ld returned 1 exit status

Applying this patch doesn't seem to affect it.
