Message:
provide HOSTCC and HOSTCFLAGS variables to simplify cross-compilation pagebundler is a helper that needs to be built with the *host* compiler because it's used to generate some sources. In normal situations, HOSTCC and HOSTCFLAGS are just ${CC} and ${CFLAGS}, but folks that cross-compile can specify there the host compiler and flags to successfully build telescope. The idea is largely based on what gforth does: it re-uses ${CFLAGS} for the host compiler though, while I'm adding an extra variable for that.
