[LTP] [RFC PATCH v2 7/7] m4: Fix warnings

[Petr Vorel]

from autoconf 2.71:

* s/AC_HELP_STRING/AS_HELP_STRING/

Similar replace was done in autoconf commit 5958ce17 ("*
doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.")
from 2.58.

* s/AC_TRY_LINK/AC_COMPILE_IFELSE([AC_LANG_PROGRAM/

Similar replace was done in autoconf commit ede91cff ("Modernize
AC_EXEEXT and AC_OBJEXT. Now work with other languages than C and C++.")
from 2.50.

Due previous keep requiring 2.61. Tested on 2.63 (SLES 11 and CentOS 6
both don't even compile as unsupported, thus we could bump version to 2.63).
