After compiling libgcrypt with -fPIC, the error has changed to this one:

/home/test/test/3/output/host/opt/ext-toolchain/bin/../lib/gcc/mips-linux-gnu/4.7.3/../../../../mips-linux-gnu/bin/ld: 
./.libs/libunzip.a(unzip.o): relocation R_MIPS_26 against `a local 
symbol' can not be used when making a shared object; recompile with -fPIC

I don't know if this is an improvement or not, and I don't know what to 
do next :/

Maybe someone else has more ideas.
