compiler (version) as a parameter of kernel_generator

[FAMILIAR-project]

Right now, compilations are made with gcc version: 6.3.0-18+deb9u1 and libc version: 2.24-11+deb9u4 We would like to have the ability to change the compiler version (still with gcc, but might even be clang in the future)

in particular, we expect that for gcc version >= 9, the size of configuration kernel can change (we've made some ad-hoc experiments with tiny kernel showing this trend)

• [x] add the parameter
• [x] handle the parameter in Python
• [x] provide custom Docker files (and build images)
• [x] send the right information to the database (wrt compiler version but also libc and so on)
• [x] tests on different configurations (eg with gcc 6.3 and gcc 9.0) and compare the sizes

Work in progress in branch :

Almost done for gcc 7 and 8 : need somes tests for be sure, specially for the informations in database.

It seem that the version 9 of GCC is only in "test" or "unstable" for debian:stretch :

Version 7, 8 and 9 work when the argument --tiny is used. But there are some errors for compile "normal" kernel.
