--------------------------+------------------------------
Our gcc toolchain's linker (ld) continues to have problems with odd
relocation issues.
We (waddlesplash) was able to work around these issues by leveraging the
clang linker (lld) to link the operating system.
While the clang linker works as expected, the gcc linker throws relocation
errors linking libbe:

waddlesplash discovered that changing the linker to the following in th
BuildConfig works around the issue:
{{{
HAIKU_LD_arm ?= /usr/bin/ld.lld ;
HAIKU_LINK_arm ?= /usr/bin/clang -fuse-ld=lld -target arm-unknown-freebsd
-shared ;
