[tlbuild] sparc-linux (bigendian?) failure in icu

[Karl Berry]

    I am fairly sure that just building from the ICU distribution will equally
    fail on sparc linux.

I just did the experiment: downloaded
http://download.icu-project.org/files/icu4c/49.1.1/icu4c-49_1_1-src.tgz
and ran

  export CFLAGS=-mcpu=v9 CXXFLAGS=-mcpu=v9 OBJCFLAGS=-mcpu=v9
  configure && make

and it did indeed fail in exactly the same way:

LD_LIBRARY_PATH=../lib:../stubdata:../tools/ctestfw:$LD_LIBRARY_PATH  ../bin/icupkg -tb ./in/icudt49l.dat ./out/icudt49b.dat
udata_swapDataHeader(): header size mismatch - headerSize 32768 infoSize 5120 length 1024
make[1]: *** [out/icudt49b.dat] Error 8
make[1]: Leaving directory `/home/1007/gu/karl/icu/icu/source/data'

Over and out on this unless a new volunteer with more energy than me
comes forward ...
