I am using glibc 2.16.0 and have no idea where this thing came from.
The binary does not run as the system's glibc (well, that very .so) is
version 2.12.
I built glibc this way:
../glibc-2.16.0/configure --prefix=/work/osmolsky/_gcc-sr-build/gcc48
--target=x86_64-unknown-linux-gnu
--with-headers=/work/osmolsky/_gcc-sr-build/sysroot/usr/include
--enable-kernel=2.6.32 --without-selinux
Just figured it out - there are a few things specific to glibc that are
vital to making a valid cross-compiler (even for my intel-to-intel case):
1) host and target should to use the same version of glibc (redhat's
source rpm also has a shash of patches)
2) glibc takes the --host argument (while I was feeding --target)
3) redhat's source rpm passes additional options to configure
So, people playing with the --with-sysroot option and building
cross-compilers must really be careful with GLibc.
