tools/Makefile force-includes include/compiler.h for every host-tool
compiler.h, and that unconditionally #include <stdint.h> in its
USE_HOSTCC.

While uint*_t are widely used, the general mechanism seems to be to
rely on compiler.h rather than explicitely including stdint.h
(but exceptions do exist)
