Grumble. Put compiler options back into CPPFLAGS for now, since they're needed to build .S files with the correct PIC options. XXX Really needs cleanup in <bsd.*.mk> to do this properly.

First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to make it work with new versions of the toolchain, etc.). This runs, but it's in serious need of cleaning and/or a fair bit of reworking. See the README file for more information, and a list of things to do.

Supply two lazy binding routines for Alpha: one that works with the old PLT format, and one that works with the new. XXX We currently always use _rtld_bind_start_old() in _rtld_setup_alpha_pltgot(). We need to add code to peek into one of the PLT entries to see which format it's in and pick the correct binding routine.

Don't put compiler options into CPPFLAGS.

Add code to peek into the PLT and determine which PLT entry format is being used.

Tidy this up a little.

LDFLAGS+= -Bshareable -Bsymbolic -e _rtld_start
* Add a linker script which provides a _GOT_END_ symbol that we can use to find the end of the GOT, rather than relying on _DYNAMIC to immediately follow the GOT. (A change in current binutils moved _DYNAMIC, and thus would have broken our Alpha ld.elf_so). * Add #ifdef'd out code to deal with the new PLT format.
