intltool-update from intltool-0.50.0 doesn't work with Perl 5.26 (and
possibly other versions later than Perl 5.22), due to "Unescaped left
brace in regex is illegal here" errors. In Perl 5.22 this resulted in
warnings, but they have since been promoted to errors.
For example, building "avahi" fails at the "prepare" stage:
checking for intltool >= 0.35.0... Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/^(.*)\${ <-- HERE ?([A-Z_]+)}?(.*)$/ at /home/abbotti/work/ptxdist/projects/dbpod-socfpga-tmp/platform-dbpod-fastpod/sysroot-host/bin/intltool-update line 1064.

configure: error: Your intltool is too old. You need intltool 0.35.0 or later.

Apply the same patch as in the mainstream Linux distros to fix it.
Note that if PTXdist updates host-intltool to version 0.51.0, it will
need the same patch.
