Hmmm... I wonder where it is looking for that file.
There ought to be one for anu userspace builds.

Missing trailing '/', and sed must be picky these days.

The makefile actually contains:

sqlite3.pc: ${SRCDIR}/sqlite3.h sqlite3.pc.in
        @(V=$$( (echo '#include <sqlite3.h>'; echo SQLITE_VERSION) | \
            ${CC} -E -I${SRCDIR} - | tail -1 | tr -d '"') && \
            ${TOOL_SED} -e s/@VERSION@/$$V/ < ${.CURDIR}/sqlite3.pc.in \
            > ${.TARGET})

So we are feeding the two lines:
    #include <sqlite3.h>
    SQLITE_VERSION
into cc -E and then assuming that the last line is the expanded version.
This is is cross build compiler, I wonder it this is being run before
the includes are 'installed'.

Since it doesn't find stdarg.h the compile fails and the last line must
be a line staring with a '#' (eg "# fubar").
The sed command isn't quoted (to the shell) so the output of $V is subject
to field splitting and generates multiple arments to sed, the first of
which is an incomplete sunstitution.

So we have four problems:

1) The compiler fails to find stdarg.h
2) The command line blindly assumes that 'tail -1' will give the right
   line.
3) The sed command doesn't quote its arguments.
4) The makefile doesn't detect errors in the sub commands.

Dunno why your system is that different!
