Install used an ABSOLUTE CMAKE_INSTALL_PREFIX (${COOKBOOK_STAGE}/usr) together
with DESTDIR=${COOKBOOK_STAGE}/stage, so everything double-nested under
stage.tmp/<abs>/stage.tmp/usr/... and libclc.pc/.bc never reached the expected
paths. Use the standard pattern: relative prefix /usr + DESTDIR=${COOKBOOK_STAGE}
(libclc.pc gets prefix=/usr, resolved downstream via PKG_CONFIG_SYSROOT_DIR);
drop the stage-flatten hack. Also relocate libclc.pc from share/pkgconfig
(upstream's DATADIR) to lib/pkgconfig (cookbook convention mesa looks up).
All 2610 GPU bitcode files already generate + install correctly.
