[uClibc] toolchain : Unrecognized target system name i386-linux-uclibc.

[Nick Jennings]

When going through the build process for the toolchain, everything goes
fine until it gets to gcc (v3.3.3 in my toolchain gcc.mk). All the patches
apply fine, then when it tries to run configure I get the following error:
Invalid configuration `i386-linux-uclibc': system `uclibc' not recognized
Unrecognized target system name i386-linux-uclibc.

I grepped through all the patches and the makefiles and found no string
'i386-linux-uclibc', so I assume this was not something that failed to get
patched into the source as a valid target system name. So what's the deal
then?
