+Subject: [PATCH] sh-conf
+
+Likewise, binutils has no idea about any of these new targets either, so we
+fix that up too.. now we're able to actually build a real toolchain for
+sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
+inept targets than that one, really. Go look, I promise).

+Subject: [PATCH] Make sure global symbol is not an indirect or warning.
+
+Problem identified in the context of glibc with latest upstream binutils.
+Dynamic symbol space was being reserved but, no actual information for the
+symbol was being set. Data for the symbol was kept initialized with -1.
+No easy test case was possible to be created.
