Section 6 of LGPL 2.1 apply. You can go with subsection a):
Accompany the work with the complete corresponding machine-readable
source code for the Library including whatever changes were used in the
work (which must be distributed under Sections 1 and 2 above); and, if
the work is an executable linked with the Library, with the complete
machine-readable "work that uses the Library", as object code and/or
source code, so that the user can modify the Library and then relink to
produce a modified executable containing the modified Library. (It is
understood that the user who changes the contents of definitions files
in the Library will not necessarily be able to recompile the application
to use the modified definitions.)

So you'd have to include the .o or .a needed to create the final shared

Or, as c): Accompany the work with a written offer, valid for at least
three years, to give the same user the materials specified in Subsection
6a, above, for a charge no more than the cost of performing this

The FAQ (http://cxx.uclibc.org/faq.html) states:
uClibc++ is released under the GNU LGPL. I am also making it available
with custom licenses for a fee. Contact me for more information. Fees
subject to the project and the phase of the moon.

Note that I'm not the author. The source specifies Garrett A. Kajmowicz.
