The following commit, 6ccd4d6, increased the RAM size for qemu machines
to 256MB due to some smart sanity tests failing on autobuilder because
more memory was needed.

Unfortunately this leads to various, potentially dangerous, issues like
the one observed during sudoku-savant project compilation:

collect: relinking
collect2: error: '_ZNK6sudoku5ClearINS_6SquareEEclERS1_' was assigned to
'board.rpo', but was not defined during recompilation, or vice versa
board.o:(.rodata+0x8): undefined reference to
`sudoku::Clear<sudoku::Square>::operator()(sudoku::Square&) const'
board.o:(.rodata+0x20): undefined reference to
`sudoku::Clear<sudoku::Sequence>::operator()(sudoku::Sequence&) const'
board.o:(.rodata+0x34): undefined reference to `typeinfo for
collect2: error: ld returned 1 exit status
make: *** [sudoku-savant] Error 1

After some tests, I found that the maximum amount of memory needed for
sudoku to compile properly is 146MB(!?!).

My attempts to create a simpler test case (using templates), in order to
replicate and isolate the issue failed. All the tests compiled just

So, my guess is that this problem is certainly memory related but the
cause might be hidden in any of the following: qemu versatile hw model,
in the kernel or, highly unlikely but not impossible, the toolchain
itself. The reason I don't really think the cause is in the toolchain is
the fact that the compilation completes just fine for 128MB on qemuarm but
also on other qemu machines (with 256MB of memory).

Since this issue might need lots of time to have a proper fix, I'll revert back
to using 128MB for qemuarm for the time being.
