bug#15678: [PATCH] compile.el: support GNU Make-4.0 directory quoting

[Jed Brown]

GNU Make commit 23c2b99e9d23e726 is part of make-4.0:

  Convert all "`'" quotes to "''" per new GNU Coding Standard guidelines.

This changes the output from

  make: Entering directory `/path/to/src'

to

  make: Entering directory '/path/to/src'

This patch teaches compile.el about the latter.
