This reverts commit ffc4afe084.
Commit from 2012 "ffc4afe084 pptp-linux: fix build with high BR2_JLEVEL
settings" added <pkg>_MAKE to a generic package, but the generic infra
does not take this symbol into account.
The build issue was fixed in 2013 with commit "a5b8081b89 pptp-linux:
fix parallel build" by adding a patch file.
So drop the bogus PPTP_LINUX_MAKE.
