I'd suggest you look at meta/classes/package.bbclass "fixup_perms" function.

The ${D}${libdir} (and above) are "corrected" to be 'root:root' by this
function.  I don't know why 'foo' would be, but if it's a standard defined
variable -- or if 'directory walking' is enabled it could end up doing this as well.

The control file for this is in meta/files/fs-perms.txt (unless otherwise
defined by a distribution or other configuration file.)

Format of the file is:

# The format of this file
#
#<path> <mode>  <uid>   <gid>   <walk>  <fmode> <fuid>  <fgid>
#
# or
#
#<path> link <target>
#
# <path>: directory path
# <mode>: mode for directory
# <uid>:  uid for directory
# <gid>:  gid for directory
# <walk>: recursively walk the directory?  true or false
# <fmode>: if walking, new mode for files
# <fuid>:  if walking, new uid for files
# <fgid>:  if walking, new gid for files
# <target>: turn the directory into a symlink point to target

The default is:

base_prefix	0755 root root false - - -
prefix		0755 root root false - - -
exec_prefix	0755 root root false - - -
base_bindir	0755 root root false - - -
base_sbindir	0755 root root false - - -
base_libdir	0755 root root false - - -
datadir		0755 root root false - - -
sysconfdir	0755 root root false - - -
servicedir	0755 root root false - - -
sharedstatedir	0755 root root false - - -
localstatedir	0755 root root false - - -
infodir		0755 root root false - - -
mandir		0755 root root false - - -
docdir		0755 root root false - - -
bindir		0755 root root false - - -
sbindir		0755 root root false - - -
libexecdir	0755 root root false - - -
libdir		0755 root root false - - -
includedir	0755 root root false - - -
oldincludedir	0755 root root false - - -

The easiest way to debug all of this is to edit meta/classes/package.bbclass,
find the following lines:

    # Debug -- list out in-memory table
    #for dir in fs_perms_table:
    #    bb.note("Fixup Perms: %s: %s" % (dir, str(fs_perms_table[dir])))

remove the '#' from the 'for' and following lines, then inspect the table from
the build logs.

Similarly, you can trace the actual fixups, by searching for def fix_perms(path,
mode, uid, gid, dir):, and removing the comment from the two bb.note entries.

This should give you an idea if this code is replacing your value with it's own.

(I give this a VERY low probability that it's a bug in pseudo.)
