However, adding -L before /usr/lib/i386-linux-gnu/. I'm compiling with
"--enable-32-bit --libdir=/usr/lib/i386-linux-gnu
--includedir=/usr/include/i386-linux-gnu" on a 64bit OS and I manually set
"export LIBDRM_LIBS=/usr/lib/i386-linux-gnu/".

After testing, I can confirm the problem comes from  "export
LIBDRM_LIBS=/usr/lib/i386-linux-gnu/". When it is not set, the build goes all
the way to the end.

LIBDRM_LIBS must contain linker flags, not just a path.

It seems to do the trick, thank you.
