Have you rebuilt libtcc1.a (e.g. "make clean" before redoing make in tcc)? 
And reinstalled it?  How did you configure tinycc?  How did you configure 
mpfr.  Because I can't reproduce:

% tcc> ./configure && make -j8
% tcc> cd /tmp/mpfr-3.1.2
% mpfr-3.1.2> CC="/matz/git/tinycc/tcc -B/matz/git/tinycc/" ./configure
...
% mpfr-3.1.2> make -j8 && make check
...
[tversion] GMP: header 5.0.2, library 5.0.2
[tversion] MPFR tuning parameters from default
PASS: tversion
====================
All 160 tests passed
(1 test was not run)
====================

(The skipped test is tget_set_d64).  In particular:

% mpfr-3.1.2> cd tests && ./texceptions
% tests> echo $?
0
% ldd ./texceptions
