Not true. automake does not have explicit support for building
programs with the host compiler when cross-compiling, but I have done
this successfully in the past when I needed precisely to build a
program on the host when cross compiling, using binutils's
BFD_CC_FOR_BUILD macro. It's a pity some version of this macro isn't
in autoconf, or even autoconf-archive; I shall do the latter.

This illustrates a weirdness of autotools: poor support for installing
interpreted languages, and also conversely for build-time compiled
programs.

This is interesting, as it doesn't match mine or commonly-reported
experience (translating my build-time programs from C to Perl made
them shorter, easier to read and fix, and no slower to run, although I
wasn't doing more than grepping 15k lines of C and writing some of it
back out again).
