+ * sysdeps/tile/tilegx/Makefile ($(cflags-mcmodel-large)):
+ Test for assembler and linker support for "-mcmodel=large -fpic"
+ in addition to compiler support; provide -DNO_PLT_PCREL if not.
+ * sysdeps/tile/start.S [NO_PLT_PCREL]: Guard for no PC-relative
+ PLT operators in assembly.
+ * sysdeps/tile/crti.S [NO_PLT_PCREL]: Likewise.
