First if you are using shared libraries, then your Config file in uClibc
is configured to build shared libraries and not static libraries.
Assuming that you have installed gcc on your embedded box, then it would
be installed in the following directories:

/usr/bin - GCC and other toolchain binaries reside here

/usr/mipsel-elf/ - Assuming your target is mipsel-elf

/usr/lib/gcc-lib/mipsel-elf/<gcc-version>/ - This directory will contain
the static and usually shared versions of libgcc.  It also contains the
various compile stage binaries such as the preprocessor.  The other
important item you will find in this directory is the *specs* file.

/usr/mipsel-elf/lib - this would contain any static C and other libraries

/usr/mipsel-elf/include - this would contain the header files for the C
library and other libraries in a cross-compiler environment

/usr/include - this would contain header files in a native compiler
environment

There are other directories present, but these are the important ones for
you.  Take a look at the specs file if necessary.  The syntax for specs
files is documented in the comments of gcc.c in the gcc source code.

Also take a look at some of the other files in uClibc, as there should be
a wrapper present for shared native environments.
