Create a symlink to sys/elf32.h, sys/elf64.h, and sys/elf_common.h.
When building libelf in the bootstrap stage this would include the tree versions of, for example, sys/_types.h. This would work as long as the tree's version of this file was close enough to the system's version of the file. If, however, there was a change in the tree such that the location of a typedef was moved this would cause problems. In this case the version of sys/_types.h in the tree no longer defines __wchar_t and expects it to to be defined in machine/_types.h, however we pick up machine/_types.h from the system and find it is not defined there. The solution is to restrict the parts of sys er include from the tree to those that are needed. This fixes the recent Tinderbox failure. Pointy Hat to: andrew
