+libluajit is having symbols that can't be
+resolved the reloc cannot accommodate an offset greater than 24 bits.
+
+Looking at libluajit with readelf -r, you see a bunch of entries that look like:
+	000082f0  00003c0a R_PPC_REL24       00000000   sqrt + 0
+
+These should not occur when the code is compiled and linked with -fPIC.
+
+It turns out that libluajit *is* compiled and linked with -fPIC, however...
+There is one assembler file called lj_vm.s which is generated during the build.
+This file is missing the `@plt' qualifier from external references.
+
+This file is generated by a program called buildvm.  This in turn uses tables
+in a file called buildvm_arch.h which is generated by dynasm.lua.
