And, configured with
cutie-pi:~/programs/gambit> ./configure 'CC=gcc-4.8 -mcpu=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard' '--enable-single-host' '--enable-shared' '--enable-multiple-versions' '--disable-gnu-gcc-no-strict-aliasing’
it takes
cutie-pi:~/programs/gambit> time make from-scratch
6085.460u 102.290s 1:43:32.86 99.5% 0+0k 5256+536568io 27pf+0w
partly because I can’t run two jobs at once (the cc1 jobs require too much memory).
