Boost-subset fails to build on RHEL

Please describe:
What you were trying to do Build vg (master branch)
What you wanted to happen Type make; get an executable some minutes later
What actually happened boost-subset fails to build, causing vowpal-wabbit build to be broken but apparently there, which causes main.o linking to fail because recalibrate_main.o depends on VW.
What data and command line to use to make the problem recur, if applicable NIH Biowulf, RHEL, attempted with GCC 6.4.0 and 7.4.0
