ICU build scripting adds some host libraries to LD_LIBRARY_PATH by
using constructs of the following form:
LD_LIBRARY_PATH="custom-path:${LD_LIBRARY_PATH}"
If the original LD_LIBRARY_PATH is empty, this causes the last search
directory be an empty string, i.e. the working directory.
ICU build runs some basic host commands (e.g. "rm") in $(TARGET_DIR)/lib
under such an LD_LIBRARY_PATH, causing target libraries (e.g. libc) to
possibly get loaded instead of host system libraries if they are
compatible enough (e.g. arch matches).
Since the target libraries may not actually be ABI compatible with host
system binaries (e.g. target has an old libc), this can cause crashes
or other errors.
Observed errors include:
(1) rm: libc.so.6: version `GLIBC_2.33' not found (required by rm)
(2) sh: line 1: 1362670 Segmentation fault (core dumped) rm -f libicudata.so.65
Workaround the issue by setting a dummy LD_LIBRARY_PATH when it would
otherwise be empty.
