@philmoz@reyalphi guys, ,
Rev 6197 stubbornly refused to boot for me on ixus70_sd1000, but I think I found what
the problem is: the CFLAGS+=etc statements (lines 28 and 35) are followed by
(line 42): CFLAGS=-fno-inline -Os -fno-strict-aliasing -fno-schedule-insns2
Since line 42 has CFLAGS= and not CFLAGS+= previous data are wiped
Moving 'Disable GCC 10...etc' and 'ifdef OPT_WARNINGS' sections down and recompiling
did the trick (attached my diff)
