Fix build of glibc 2.29 on systems with obsolete host programs
- Force building make as a companion tool if host make is older than 4.0 (CentOS 7 currently has 3.82) - Disable 2.29 as a choice if host python is older than 3.4 (CentOS 7 has 2.6 unless python from EPEL is installed) - Python2 emits its version information to STDERR. Ugh. While there, also use the detected host Python for GDB configuration. Signed-off-by: Alexey Neyman <stilor@att.net>
