I just checked and EXTRA_OECONF is not correctly expanded. It is missing 
the "ac_cv_sizeof_off_t=8" part that is present on the Ubuntu machine.

On Ubuntu:
EXTRA_OECONF="--without-libidn --enable-crypto-auth                 
--disable-ldap --disable-ldaps 
--with-ca-bundle=/etc/ssl/certs/ca-certificates.crt ac_cv_sizeof_off_t=8 
--with-gnutls --enable-ipv6 --without-libssh2 --without-librtmp 
--disable-smb --without-ssl 
--with-zlib=/scratch/working/build/tmp/sysroots/fos4x/usr/lib/../"

On Debian:
EXTRA_OECONF="--without-libidn --enable-crypto-auth                 
--disable-ldap --disable-ldaps 
--with-ca-bundle=/etc/ssl/certs/ca-certificates.crt  --with-gnutls 
--enable-ipv6 --without-libssh2 --without-librtmp --disable-smb 
--without-ssl 
--with-zlib=/data/jenkins/workspace/kOS/build/tmp/sysroots/fos4x/usr/lib/../"

On both machines /bin/sh is pointing to /bin/bash.
