[OE-core] one more question about FILESPATH and eglibc, if i might

[Robert P. J. Day]

  as one more data point in what looks like weird and sometimes
unnecessary settings of FILESPATH in recipe files, i give you this
from eglibc_2.18.bb:

FILESPATH = "${@base_set_filespath([ '${FILE_DIRNAME}/eglibc-${PV}',
'${FILE_DIRNAME}/eglibc', '${FILE_DIRNAME}/files', '${FILE_DIRNAME}'
], d)}"

  first, it would seem that the first three elements in that list
match *exactly* what you'd get from the default setting of FILESPATH
from base.bbclass, would it not?

FILESPATH = "${@base_set_filespath(["${FILE_DIRNAME}/${BP}",
"${FILE_DIRNAME}/${BPN}", "${FILE_DIRNAME}/files"], d)}"

so it's not clear what the point of that explicit setting is.

  in addition, what's with the addition of that fourth list entry:
${FILE_DIRNAME}? all that's going to do is extend FILESPATH with the
OVERRIDES-related directories *immediately* under the eglibc
directory, and i don't see what value that has. here's the final value
of FILESPATH for eglibc as displayed by "bb show":

FILESPATH="/home/rpjday/oe/dora/poky-dora-10.0.0/meta/recipes-core/eglibc/eglibc-2.18/arm

/home/rpjday/oe/dora/poky-dora-10.0.0/meta/recipes-core/eglibc/"

and i don't see the point of those last five entries. is the use of
${FILE_DIRNAME} as a fourth argument to base_set_filespath()
deliberate? and what is it for? thanks for your patience.
