[Mesa-dev] [PATCH] Fix --enable-XX-bit flags by moving LT_INIT where it should

Moving LT_INIT after setting completely (AM_)C(XX)FLAGS and LDFLAGS.
LT_INIT needs them as they are expected to be used all along 
the compilation when the macro runs its tests to determine among other 
things the host type.

For info, see http://www.gnu.org/software/libtool/manual/html_node/LT_005fINIT.html
