BUILD: makefile: fix expression again to detect ARM platform

I messed up the fix in 67b095e ("BUILD: makefile: fix regex syntax in
ARM platform detection"), I tried it by hand in the shell without "-v"
but left it in the expression. It works on ARM because it only finds
lines starting with '#' but on other platforms it insists for -latomic.
