Comment (by raimue):

 The attached patch proposes an update to gcc 7.1.0 and newlib 2.5.0.
 However, the resulting destroot looks like it will very likely conflict
 with the native gcc on `${prefix}/lib/libcc1.so`. Most probably this needs
 a patch to move libcc1 to the appropriate subdirectory. Other
 distributions might already have it, but I have not looked.
