stack @2.1.3_0: segfaults on 10.7.5

[kencu (Ken)]

the currently available stack port doesn't build on 10.7.5 due to a segfault, and if the -bootstrap version is installed, it (no surprise) segfaults as well. Clearly the downloadable binary doesn't work on older systems (vintage TBA).

$ port -v installed stack
The following ports are currently installed:
  stack @2.1.3_0-bootstrap (active) platform='darwin 11' archs='x86_64' date='2019-09-29T18:06:24-0700'
$ /opt/local/bin/stack
Illegal instruction: 4

I generated a new version of stack on 10.6.8 that runs properly on all older x86_64 systems, and replaced the binary in the stack -bootstrap port with that.

Using that working version of stack, pandoc will install without trouble (although it takes just forever to build):

$ port -v installed pandoc
The following ports are currently installed:
  pandoc @2.7.3_0 (active) platform='darwin 11' archs='x86_64' date='2019-09-29T22:10:02-0700'
