automake: fix do_compile error when perl is under a very long path

Fixed:
bitbake automake-native failed with error:
| :; HELP2MAN_NAME="Generate Makefile.in files for configure from Makefile.am"; export HELP2MAN_NAME; LONGPATH/tmp/hosttools/mkdir -p doc && AUTOMAKE_HELP2MAN=true ./pre-inst-env LONGPATH/tmp/hosttools/perl ../automake-1.17/doc/help2man --output=doc/automake-1.17.1 --info-page=automake --name="${HELP2MAN_NAME}" bin/automake-1.17
| help2man: can't get `--help' info from bin/aclocal-1.17
| Try `--no-discard-stderr' if option outputs to stderr
| make: *** [Makefile:3818: doc/aclocal-1.17.1] Error 2

In above command,  `bin/aclocal-1.17 --help` will be runned, since
@PERL@ is replaced as the full path of perl, it is possible that the
shebang line exceeds the max limit and causes above error, because the
kernel imposes a maximum length on the text that follows the "#!"
characters at the start of a script; characters beyond the limit are
ignored.  Before Linux 5.1, the limit is 127 characters.  Since Linux
5.1, the limit is 255 characters.

Add back the forced perl settings and add a patch for workaround the
fatal error caused by space in perl path
