[OE-core] BB_NO_NETWORK = "1" causes fetch to fail for unnecessary u-boot parsing

[Robert P. J. Day]

  not sure if this is expected behaviour, but i'm using the meta-ti
layer to build a core-image-minimal for a am180x-evm.  i'm using
"own-mirrors" to use my own premirrors directory and i've collected
all of the necessary tarballs and actually completed the build, after
which i make sure i have saved all of the tarballs so i don't need
to download anything for a subsequent build.

  as a test, i totally delete my build and start over, but this time
with

  BB_NO_NETWORK = "1"

which i assumed would still work.  instead, i almost immediately got
this:

$ bitbake -c fetch core-image-minimal
Pseudo is not present but is required, building this first before the
main build
ERROR: ExpansionError during parsing
/home/rpjday/oe/dist/layers/meta-ti/recipes-bsp/u-boot/u-boot_2013.01.bb:
Failure expanding variable SRCPV, expression was
${@bb.fetch2.get_srcrev(d)} which triggered exception NetworkAccess:
Network access disabled through BB_NO_NETWORK but access requested
with command git ls-remote
git://arago-project.org/git/projects/u-boot-keystone.git
DEV.MCSDK-03.00.00.06 (for url None)
ERROR: Command execution failed: Exited with 1

  that's not even the version of u-boot that's going to be used, as
"bitbake -s" shows:

u-boot  :2009.11+r68+gitr5f16b8551b125f16cd8d58f278cb25b94272fd9f-r68

so i'm guessing that what's happening here is that even though the
u-boot recipe file u-boot_2013.01.bb will contribute nothing to this
build, its parsing alone requires network access, which makes the
usage of BB_NO_NETWORK = "1" somewhat useless in this context.

  am i misreading something?  thoughts?
