Three separate defects, one per class:
1. script.rs passed autoreconf only -I${COOKBOOK_HOST_SYSROOT}/share/aclocal, so
macros installed by a DEPENDENCY into the per-recipe sysroot were invisible.
util-macros was built and declared as a dependency, yet configure still said
configure.ac:10: error: must install xorg-macros 1.16.0 or later
Now also searches ${COOKBOOK_SYSROOT}/usr/share/aclocal and exports
ACLOCAL_PATH. Fixed generically -- every autotools recipe benefits.
2. Upstream builds test/test_xcb_image_shm unconditionally (Makefile.am:15
SUBDIRS = image test) and it needs SysV shared memory, which Redox lacks.
The library itself does not: configure only probes sys/shm.h and adapts. So
dropping test/ removes a test binary, not functionality.
3. libxcb is a STATIC archive here, so its libXau/libXdmcp dependencies do not
propagate to consumers as a shared library's DT_NEEDED would:
xcb_auth.c: undefined reference to `XauGetBestAuthByAddr'
Named them via LIBS, not LDFLAGS: autoconf emits LDFLAGS BEFORE the objects
and LIBS AFTER, and a static archive only satisfies symbols referenced by
objects preceding it. With -lXau in LDFLAGS the link still failed while
libXau.a sat in the sysroot. Same ordering rule as -lgcc in
redox-toolchain.cmake and -licudata in plasma-workspace -- third occurrence.
Verified: cook xcb-util-image - successful, libxcb-image.a staged.
