Minor fix for OSX

[SkyToGround]

This minor fix makes it possible to compile e3-base under MacOSX and should have no (as far as I can tell) negative effects when building under Linux.

I'm not a maintainer of this repository.

I just want to mention that if you want to install epics-base on OSX, I'd recommend using conda. I updated the epics-base feedtstock on conda-forge last week: conda-forge/epics-base-feedstock#6
epics-base 7.0.3.1 conda package is available on Linux, OSX and Windows.

@beenje Thanks for the tip. I am sad to say though that I have been tasked with sorting out a runtime bug in an EPICS driver which means running it under a debugger. The instructions for building the driver is to do so using e3 hence the current predicament.

I'd then really recommend that you try debugging that under Linux. You can do that in the Development Machine.

I would very much prefer to sort out the issue using the debug tools and development environment that I am familiar with so I am willing to wait until next week for someone to look at this PR. Alternatively, are you willing to sort out the bug @beenje in ADKafka? 🙂

The problem is that I'm quite sure that there are many other things to fix to make E3 work on OSX. Compiling e3-base should be easy. But compiling modules using require driver.makefile is probably not trivial.
Regarding ADKafka, you should maybe contact Douglas. I know he created a conda package (linux only): https://gitlab.esss.lu.se/utgard-deploy-sandbox/module-recipes/adkafka-recipe
