Off by default, build behaves normally.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.
- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.
It is obvious that its modification time will change with each such file
builded.
This bug cause whole libelf to rebuild itself each second make run
(and relink that files on each first make run) in the loop.
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.

objects inside one ELF section, which prevents the creation of a ELF
section with mixed data types. For example, gcc LTO use libelf to
create a .gnu_lto_XXX section that contains integers and a string
table, which doesn't work with our libelf implementation.
The changes made in this commit include:
* Allow Elf_Data type to be different than section type.
* Relax Elf_Data alignment check.
* Align each Elf_Data by their own alignment instead of section alignment.
