runqemu: set qemuarm memory size back to 128MB
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 sudoku::Action<sudoku::Sequence>' ...AND THE LIST CONTINUES... 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 fine. 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.
