- get rid of building an a.out-happy ldd (but keep supporting a.out
binaries for the ELF version.) - convert a.out, elf32 and elf64 support into convience libraries and link them right ones in. if elf_ldd() fails on 64 bit platforms, try elf32_ldd() before aout_ldd(). now ldd on 64 bit platforms works for 32 bit binaries, aka PR#40199, and it seems that all the issues from README are gone too.

BUGS/PROBLEMS:
|
||||
|
||||
* Reports "ldd: mmap of entire address space failed: Cannot allocate memory",
|
||||
or erroneously reports that libraries cannot be found,
|
||||
when run on many files (`ldd /usr/bin/*').
|
||||
|
||||
|
||||
TO DO:
|
||||
|
||||
* Support for executable formats other than ELF.
|
||||
|
||||
* Support for coexistence of 32-bit and 64-bit ELF.
