As written in a previous mail, I'm trying to adjust meson to provide

For xorg-sgml-doctools, there was a small discrepancy if the user was
not selecting the defaults. This is easy to fix (diff attached), but I
now wonder about pkgconfig .pc files directory.
In generated aclocal.m4, pkgconfigdir is said to be, by default,
${libdir}/pkgconfig, and supposed to be settable with
--with-pkgconfigdir (it is not settable in fact: the option is not
recognized).
We put .pc files in ${datadir}/pkgconfig. By default, datadir ==
datarootdir, but this can be changed (with AC) so that X11 stuff is
put in a dedicated subdir, while pkgconfig files are reachable in a
more general dir.
In fact, on my OS (NetBSD), pkgconfig files are placed in
${libdir}/pkgconfig and not ${datarootdir}/pkgconfig.
So is there some rule about this for X11 stuff?
X11 follows the general rules for pkg-config file installation:
${libdir}/pkgconfig for architecture-specific stuff,
${datarootdir}/pkgconfig for architecture-independent stuff.
Normally this means if your pkgconfig file specifies linking against a
library, it goes in ${libdir} so it gets the settings right for whatever
library you're actually linking against (32-bit vs. 64-bit, cross-compiling
for another architecture, etc.).
Stuff that ends up in ${datarootdir}/pkgconfig tends to be the same for
all OS'es/CPU's, things like the xorgproto header files and the
xorg-sgml-doctools XML files, and isn't used in linking binaries.
