[Bug 233707] www/firefox: fails to build with -fstack-protector-{strong,all} + -Wl,-z,nocopyreloc

--- Comment #4 from Jan Beich <jbeich at FreeBSD.org> ---
Default SSP_CFLAGS appear to cancel -fstack-protector-strong, so the port
builds fine: https://ptpb.pw/G4f6

Upstream build isn't so fortunate:

$ pkg install python27
$ hash git 2>/dev/null || pkg install mercurial
$ hg clone https://hg.mozilla.org/mozilla-unified firefox ||
  git clone https://github.com/mozilla/gecko-dev firefox
$ cd firefox
$ hg update central || git checkout origin/master
$ ./mach bootstrap # select Firefox for Desktop
$ ./mach build
[...]
checking for clock_gettime(CLOCK_MONOTONIC)... no
[...]
mozbuild.frontend.reader.BuildReaderError:
==============================
FATAL ERROR PROCESSING MOZBUILD FILE
==============================
The error occurred while processing the following file:
    /path/to/mozilla-central/mozglue/misc/moz.build
A moz.build file called the error() function.
The error it encountered is:
    No TimeStamp implementation on this platform.  Build will not succeed

(In reply to Dimitry Andric from comment #1)
> Maybe a workaround is to compile firefox with -fPIE? :)

$ CFLAGS=-fPIE CXXFLAGS=$CFLAGS ./mach build
