Using 'CPPFLAGS="-m64" LDFLAGS="-m64"' does not work:
configure fails with "compiler unable to create executables"
because gcc does not accept "-m64".

The gcc is:

$ uname -a
AIX power8-aix 2 7 00FA74164C00

$ gcc -v
Using built-in specs.

The following command did work to build 64bit binaries:
    ./configure CFLAGS=-maix64 LDFLAGs=-maix64 AR="ar -X64"

The AR is required, otherwise creating libcoreutils.a fails with:
===
ar: 0707-126 lib/vasprintf.o is not valid with the current object file mode.
Use the -X option to specify the desired object mode.
===

With using this command compilation succeeds, and few tests fail:
  FAIL: tests/misc/help-version
  FAIL: tests/misc/shred-remove
  FAIL: tests/misc/stdbuf
  FAIL: tests/install/basic-1
  FAIL: tests/mkdir/p-3
  ERROR: tests/tail-2/pipe-f
  FAIL: tests/touch/trailing-slash
Full log attached.


Also, the other alternative of accepting 32bit time also worked:
   TIME_T_32_BIT_OK=yes ./configure
With this command, the same tests still fail (log attached).


I wonder if this is worth mentioning in the README
(which has two sections about building on HPUX and OSF/1).
