Comment 12 for bug 1862053

the file from icu 65.1 is built using

g++ -v -Wdate-time -g -O3 -fstack-protector-strong -Wformat -Werror=format-security -W -Wall -pedantic -Wpointer-arith -Wwrite-strings -Wno-long-long -std=c++11 -c -o genmbcs.o genmbcs.ii

no specific patches applied for the trunk. The compiler defaults to PIE, and the usual hardening defaults:

/usr/lib/gcc/powerpc64le-linux-gnu/10/cc1plus -fpreprocessed genmbcs.ii -msecure-plt -quiet -dumpbase genmbcs.ii -mcpu=power8 -auxbase-strip genmbcs.o -g -O3 -Wdate-time -Wformat=1 -Werror=format-security -Wextra -Wall -Wpedantic -Wpointer-arith -Wwrite-strings -Wno-long-long -std=c++11 -version -fstack-protector-strong -fasynchronous-unwind-tables -fstack-protector-strong -Wformat-security -fstack-clash-protection
