It seems adding another 1Gb of swap did not helped, at least without
full rebuild

https://github.com/gcc-mirror/gcc/blob/master/libgcc/libgcc2.c

seems that _divdc3 function is for complex number divide, in case soft

Because Linux  dropped sparc32 support it might be possible that
native compilation on sparc32 somewhat bitroted in at least gcc10 + ?
