SUMMARY: AddressSanitizer: 8192 byte(s) leaked in 2 allocation(s).

Replace AC_FUNC_MMAP with GCC_AC_FUNC_MMAP to avoid the sanitizer
configure check failure.

19e559f1c9 libsframe: add the SFrame library 
libsframe is a library that allows you to:
- decode a .sframe section
- probe and inspect a .sframe section
- encode (and eventually write) a .sframe section.

This library is currently being used by the linker, readelf, objdump.
This library will also be used by the SFrame unwinder which is still
to be upstream'd.

The file include/sframe-api.h defines the user-facing APIs for decoding,
encoding and probing .sframe sections. A set of error codes together
with their error message strings are also defined.

Endian flipping is performed automatically at read and write time, if
cross-endianness is detected.

ChangeLog:

	dependencies.
	* Makefile.in: Regenerated.
	* binutils/Makefile.am: Add libsframe.
