PR binutils/3384
* configure.in (AC_CHECK_HEADERS): Add limits.h and sys/param.h.
* configure: Regenerated.
* config.in: Likewise.
* readelf.c: Include <limits.h> and <sys/param.h> for PATH_MAX.
(program_interpreter): Allocate PATH_MAX bytes instead of 64.
(process_program_headers): Don't assume that program interpreter
is shorter than 64 characters.
