Diff from glimpse-4.18.5.ebuild
Takes care of two things. First, the LDFLAGS issue as seen by the additional sed.
I also believe I resolved the parallel make issue, however, this is harder to confirm. I was unable to cause it to break on my machine using anywhere from 2 to 20 jobs so I'm fairly sure it is working as it should be. This fix is provided by the patch that I will attach shortly.

Patch forces the sub-directories (which contain dependencies for the main directory) to compile first instead of along with. Should resolve any parallel compilation issues.
