target-lm32: fix debug memory access

CPU models which have the LM32_FLAG_IGNORE_MSB flag set will shadow the
lower 2GB to the upper 2GB memory space. This will fix the debug memory
access used by qemu console and GDB to match this behaviour.

target-lm32: flush tlb after clearing env

The tlb data is stored within the CPU env. Therefore, the initialization
has to be done after we clear the environment. Otherwise the tlb will have
a valid entry for address 0x0.

configure: proper OpenGL/GLX probe

Probe for GL and GLX symbols and X11 library. This fixes a build error

configure: rename OpenGL feature to GLX

As the probe now actually checks for the availability of GLX, rename it
accordingly. The only user of this feature is the milkymist-tmu2 model.
