# Lacros is built with "{arch}-generic" configuration. However, in Chrome
# OS, it is just "one board variation", so the libraries on the *-generic
# boards may not be compatible with the ones on the actual DUTs.
# One of the common pattern recently we hit is symbols exposed by libgcc.
# The symbols start to be exposed recently because of libunwind transition
# and along with it they are or are not re-exposed by other libraries, too,
# depending on per-board implementation.
# To mitigate the situation, marking -shared-libgcc to look up the system
# libgcc always.
