[OE-core] Performance datapoint - impact of static libs

[Richard Purdie]

Before:

real	104m1.135s
user	415m57.560s
sys	61m31.180s

With "--disable-static" being passed to configure (changes below):

real	99m46.645s
user	383m32.390s
sys	60m42.170s

So static libs add an extra ~30mins of processing (7%) and ~5 mins to
the overall build time. Not as much of a gain as I'd have liked but
interesting none the less.

The changes were effectively:

DISABLESTATIC = "--disable-static"
DISABLESTATIC_pn-sqlite3-native = ""
DISABLESTATIC_pn-openssl = ""
DISABLESTATIC_pn-openssl-native = ""
DISABLESTATIC_pn-qemu-native = ""
EXTRA_OECONF_append  = " ${DISABLESTATIC}"

in local.conf with a patch to the openjade-native recipe to not install
the .a file using oe_libinstall and a patch to apmd to fix a libtool
related compiling bug in its makefile.

Cheers,

Richard
