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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
