Hi!

I've been maintaining GNUnet packages on OpenWrt for the past decade. By
nature everything in OpenWrt is built by cross-compilation, which used
to work ok-ish with the autotools-based buildsystem -- sometimes I had
to patch a little test or tweek ac_* variables, but in general this
allowed for GNUnet to be available on a vast variety of hardware
targets, on various different ARM, AArch64, MIPS(el), MIPS(el)64,
Loongarch64, PPC, PPC64, RISC-V 64, ... SoCs with and without FPUs,
dedicated builds for each popular core, nicely split into more or less
atomic packages.

I'm excited to see GNUnet made the switch to meson, which is defintely a
step forward, however, I needed to make a bunch of changes to the meson
beuild because the meson script requires executing compiled things on
the buildhost, which obviously won't work in a cross-compilation
environment. In this series I'm addressing this by converting all
run-time tests into compile-time tests.

I've also added an opt-out option for not building the handbook, as the
absence of the 'makeinfo' tool would make the meson install phase fail
otherwise (and as you can imagine it anyway doesn't make sense to ship
the handbook for embedded devices).

Last but not least I've also restored building the 'flat' namecache
plugin and made sure the SQL source files for namecache get installed
like they did with the autotools based build.

I would have loved to just push all this into the git repository,
however, it looks like my write access has been revoked. Hence I'm
sending those 8 patches here on the mailing list and hope you can just
`git am` them.
