[OE-core] Some further build dependency timings

[Richard Purdie]

Just for reference, with a base configuration, sato image:

real	50m8.223s
user	298m41.450s
sys	52m42.200s

adding:

ASSUME_PROVIDED =+ "bison-native flex-native sqlite3-native git-native"

(and hacking the pseudo recipe to use a sqlite3-native):

real	42m6.740s
user	296m21.940s
sys	52m25.220s

We continue to have real dependency issues around gettext in both the
native and target builds...

Cheers,

Richard
