[dunfell][PATCH] icu: backport fix for rare random genrb segmentation fault

["Martin Jansa" <Martin.Jansa@gmail.com>]

* sometimes I've seen it also reporting "Bus error" instead of segmentation fault

* upstream bug report:
  https://unicode-org.atlassian.net/browse/ICU-21175

* on 80 core machine it failed 11 times in 1000 rebuilds of icu in various files:
  icu.019.stderr.compile:make[1]: *** [out/build/icudt66l/windowsZones.res] Segmentation fault
  icu.035.stderr.compile:make[1]: *** [out/build/icudt66l/supplementalData.res] Segmentation fault
  icu.095.stderr.compile:make[1]: *** [out/build/icudt66l/plurals.res] Segmentation fault
  icu.116.stderr.compile:make[1]: *** [out/build/icudt66l/curr/supplementalData.res] Segmentation fault
  icu.313.stderr.compile:make[1]: *** [out/build/icudt66l/supplementalData.res] Segmentation fault
  icu.415.stderr.compile:make[1]: *** [out/build/icudt66l/supplementalData.res] Segmentation fault
  icu.476.stderr.compile:make[1]: *** [out/build/icudt66l/metadata.res] Segmentation fault
  icu.495.stderr.compile:make[1]: *** [out/build/icudt66l/supplementalData.res] Segmentation fault
  icu.496.stderr.compile:make[1]: *** [out/build/icudt66l/supplementalData.res] Segmentation fault
  icu.505.stderr.compile:make[1]: *** [out/build/icudt66l/pluralRanges.res] Segmentation fault
  icu.756.stderr.compile:make[1]: *** [out/build/icudt66l/numberingSystems.res] Segmentation fault

* apply 0001-Fix-big-endian-build.patch in do_patch like this new patch
