So to continue the story, adding:

DEBUG_FLAGS = ""
INHERIT_INSANE = ""
PACKAGE_CLASSES = "package_ipk"
USER_CLASSES = ""

Results in:

real	38m23.053s
user	237m7.430s
sys	39m3.720s

Then adding PSEUDO_RELOADED=yes to the environment of tasks not needing
pseudo (hack patch below):

real	36m20.683s
user	236m19.580s
sys	37m54.450s

Finally, adding:

DISABLESTATIC = "--disable-static"
DISABLESTATIC_pn-qemu = ""
DISABLESTATIC_pn-qemu-native = ""
DISABLESTATIC_pn-openssl = ""
DISABLESTATIC_pn-openssl-native = ""
EXTRA_OECONF += "${DISABLESTATIC}"

real	34m53.877s
user	233m34.780s
sys	38m50.190s

Cheers,

Richard
