In Debian Stretch/Testing gcc version 7 is called gcc-7 and g++-7 and 'gcc -dumpversion' returns '7' which causes 'make defconfig' to fail with
Build dependency: Please install the GNU C Compiler ... Build dependency: Please install the GNU C++ Compiler ... The following patch is minimal invasive. Alternatively, it would be more robust to use the regex '^(4\.[8-9]|5\.[0-9]|6\.[0-9]|7($$$$$$$$|.\[0-9]))' instead (currently even 1.4.0 would be accepted), but this might have backward-compatibility ramifications.
