[pi4] crash w some games

[nemo93]

hello, I recently tried Mame2016 on a pi4 and was quite amazed by the excellent results. All games tested ran fullspeed (except for some 3D games of course).

My setup: pi4, buster (all packages upgraded as of 6/8/2020), no overclock, mame 0.174 collection rebuilt from a 0.185 version. Retropie 4.6.

However some games refused to work:

• 1942 => crash with a segmentation fault message (no issue with Mame2003plus)
• brapboysj => does run however stuck in a loop during bootup process (no issue with Mame2003plus)
• cabal => does run yet no control working (no issue with Mame2003plus)
• ddcrew => does run yet no control working (no issue with Mame2003plus)
• cyvern/dragnblz => => crash with no specific message (no issue with Mame2003plus)
• gunbird2 => crash with no specific message (no issue with Mame2003plus)
• hharry => crash with no specific message (no issue with Mame2003plus)
• kungfum => crash with no specific message (no issue with Mame2003plus)
• guardian => seems to run once in a while (no issue with Mame2003plus)
