Yes that's the solution.
zlib-1.2.5 already has -fPIC where needed
When you have -fPIE on unmodified gcc specs, that cause TEXTREL.
But what caught me was that I look on other boxes where I compile with same
CFLAGS and didn't find the TEXTREL on same libz.so-1.2.5
That was wrong and same TEXREL is everywhere.
