log.do_configure

If any component of the directory structure contains the string 'yes', eglibc will fail to build properly because the configure script incorrectly thinks it is being built for hard-float ABI.  This causes the configure part of do_populate_sysroot to later fail.  It seems that the check for hard-float ABI is broken or at least broken the way it is invoked by bitbake?

I initially hit this error when a certain user could not build, but all others on the same build server could.  I narrowed it down to the fact that the username contained the string 'yes' (and therefore the home dir) and was able to reproduce it with any directory containing 'yes' in the name.

Version tested:
http://downloads.yoctoproject.org/releases/yocto/yocto-1.5.2/poky-dora-10.0.2.tar.bz2

Build system: Ubuntu 12.04 x86_64

Steps to reproduce:
mkdir diryes
cd diryes; tar xzvf poky-dora-10.0.2.tar.bz2
cd poky-dora-10.0.2
MACHINE=qemuarm bitbake eglibc

Is this an upstream issue with the hard-float check in eglibc?  Or something specific to how it is being built in OE-Core?
