Compile error when STATIC_LINK=true

[davised]

Hi there,

I'm compiling using gcc 7 on centOS 7 using the STATIC_LINK=true flag.

$ make STATIC_LINK=true
*** Detecting g++ version 7 ***

I fixed the error in the makefile, PR incoming.

Incidentally, the gcc 4.8.5 was incorrectly determined to be g++ 12+ or something. Not sure how that happened, but it wasn't an issue when I used gcc 7 from devltoolset-7.

Two other things:

1. There is extra whitespace in the makefile. Doesn't break anything but it bugs me. Maybe it doesn't bug you, and I didn't remove it in the PR though!
2. If you download the source .tar.gz from a release, I get an error during compilation that there is no git repo in the directory. Compilation still continues. I assume this is because of the -DGIT_COMMIT part of the compilation.
