While doing a configure for glibc, it is expected that you normally provide an alternative –prefix, because installing to the default location ( /usr/local) can potentially cripple the system.
How to link GCC to test install glibc?
To link a program with a test-install glibc, you need to specify the gcc setup. This is done by using the option “-b i486-linuxglibc2”. For most programs, you can specify these new options by adding them to the $CFLAGS and $LDFLAGS makefile options:
Can a compiled program be linked to glibc?

Which is the primary library in glibc 2?
