[oe] why does glibc_2.9.bb use glibc-ports-2.7?

[Graham Gower]

This combination of glibc-2.9 with glibc-ports-2.7 fails to build on mipsel.

I assume there is either a problem with the glibc-ports-2.9 on arm, or the
recipe was simply copied from glibc_2.7.bb without noticing that the ports
version was hardcoded.

I'm using the following patch on mipsel without problems. I don't know what
needs to be done for the other architectures, so it shouldn't be committed.

-Graham

PS: eglibc-2.9 and eglibc-2.10 both fail with a nasty error:
/home/grg/oe/tmp/work/mipsel-angstrom-linux/eglibc-2.9-r4.2/build-mipsel-angstrom-linux/libc_pic.os: In function `_mcount':
(.debug_macinfo+0x5bafe18): relocation truncated to fit: R_MIPS_HI16 against `_gp_disp'
