This allows programs run through gcompat to fork and re-exec themselves.
It fixes readlink("/proc/self/exe") to return the executable's absolute
path, instead of musl's path.

This takes advantage of the (lack of a) musl implementation for
simplicity.

On musl pread and pread64 are the same thing.

The other unimplemented signal function in LSB is sigreturn, with is not
really implementable.

This follows the exceptionally-detailed functional description in the

* Add all (non-wchar) stdio functions from LSB, plus those found in use
in other applications. Document those functions from LSB as such.
* Use a consistent structure and paramater names for all functions.
* flag == 0 means FORTIFY_SOURCE=1, so the implemented checks should be
unconditional.
* Add all possible checks without parsing the format string.
* Move functions from wchar.h to their own appropriately-named file.

Like fgetpwent_r/getpwent_r, these require a deep copy of the structure
into the caller-provided buffer. This is nontrivial for the array of
strings member.
getgrent_r is required by LSB.
[NOTE: I'm not too happy with the macro, but it works. Any suggestions?]

Changes to existing code:
* Make explicit comparison against NULL.
* Adjust debug message for readability.

Rename the file to match the header it implements functions from.
Changes to existing code:
* Fix the return value from backtrace (off by one).
* Use __builtin_extract_return_addr as recommended in gcc documentation.
* Document header usage.
* Document where the functions are referenced in the LSB standard.

* Remove -DPIC as it is unused (and PIC is always enabled).
* Export the loader name as a macro (this will be used in the future).
* Enable compiler warnings, except the expected ones.

* Prefer providing the underscore-prefixed symbol as the strong
definition.
* Do not use a weak alias if the alias is also underscore-prefixed.
* Make libgcompat objects depend on the new header.
[NOTE: I originally took the weak_alias macro from musl's libc.h, but
it's trivial and the same pattern already in use. If desired, I
can add the musl copyright notice.]

On GCC 4.9.4, at least backtrace.c fails to compile because of variable
declaration in a for statement, which requires -std=c99 or -std=c11.
Since we are using ISO C mode instead of a GNU standard, we additionally
must define _BSD_SOURCE to expose Dl_info for the dl code.
