* exec/exec.c (insert_args, exec_0): On non-MIPS systems, copy
NAME and its length to the loader area. State that MIPS support
is not yet available (though it will be pending the availability
of a functioning emulator).
* exec/loader-aarch64.s (_start):
* exec/loader-armeabi.s (_start):
* exec/loader-x86.s (_start):
* exec/loader-x86_64.s (_start): Displace auxv, environ, and
argv to create sufficient space for the provided file name, and
copy the file name there. Replace AT_EXECFN to refer to this
space.
* exec/Makefile.in (.SUFFIXES): Include ., then `srcdir'.
* exec/loader-aarch64.s (_start):
* exec/loader-armeabi.s (_start):
* exec/loader-mips64el.s (__start):
* exec/loader-mipsel.s (__start):
* exec/loader-x86.s (_start):
* exec/loader-x86_64.s (_start): Get basename of opened exec
file and make it the command name. Fix envp skipping on x86
and various leaks.
