tools/automake: hardcode portable location for Perl
The latest automake version 1.17 includes a restriction against whitespace
for the configure variable $PERL, which is set to "/usr/bin/env perl"
for portability reasons with products like the SDK.
Instead of waiting until the next version of automake is released
for this error to be converted to a warning,
set the shebang of automake and aclocal manually with a patch.
In past git history, these lines have been patched before,
but only to remove the "-w" flag in favor of setting global warnings
in the script itself so that env does not strip the option.
The other purposes of Perl during building can use
the static staging directory path without any limitations.
Also, the configure variable "am_cv_prog_PERL_ithreads"
for the detection of Perl threads support
has been removed since 2013 in favor of dynamic runtime detection.
Remove our manual setting of this variable value as it has no effect.
