Crap...I missed a command. The corrected series of
commands...post-libgcc-object-build... is at the end of this email.
Again, please let me know which of the commands I should run...or if
ishould run all of them...sooner rather than later. Having both build
dirs on device seriously limits other tasks I can perform.
In the command below, '*.o'is a placeholder for a huge list of objects
in the arm-linux-androideabi/libgcc tree
# Early copyback; see "all" above for the rationale. The
# early copy is necessary so that the gcc -B options find
# the right startup files when linking shared libgcc.
