# The emulator code needs to be built with a local fpu_reg.h instead of
# the one in ${EMUFLOAT_DIR}.  Unfortunately, C preprocessor semantics
# means that a header file in the same directory as the source file
# overrides any alternative header file location.  In order to include
# the wanted header file, create symlinks pointing to the real files
# and compile through the symlink.
