PR27716, build failure for msdosdjgpp: PATH_MAX undeclared
We shouldn't be using arbitrary limits like PATH_MAX in GNU programs.
This patch also fixes some memory leaks in readelf when processing
separate debug info.
PR 27716
binutils/
* objdump.c (show_line): Don't limit paths to PATH_MAX.
* readelf.c (struct filedata): Change program_interpreter from
a char array to a char pointer.
(process_program_headers): Sanity check PT_INTERP p_filesz.
Malloc program_interpreter using p_filesz and read directly from
file.
(process_dynamic_section): Check program_interpreter is non-NULL.
(free_filedata): New function, split out from..
(process_object): ..here.
(close_debug_file): Call free_filedata.
* sysdep.h: Don't include sys/param.h.
(PATH_MAX): Don't define.
* configure.ac: Don't check for sys/param.h.
* configure: Regenerate.
gprof/
* gprof.h (PATH_MAX): Don't define.
* corefile.c (core_create_line_syms): Don't use PATH_MAX for initial
file name size.
* source.c (annotate_source): Malloc file name buffer. Always
trim off "-ann" when dos 8.3 annotate file matches original.
* utils.c (print_name_only): Malloc file name buffer.
