--- Comment #2 from sebastian.huber at embedded-brains.de ---
In the referenced GCC file, the sed expression is constructed in several steps,
one input is

hardfp_float_modes := sf df

which is transformed via

hardfp_mode_regexp := $(shell echo $(hardfp_float_modes) | sed 's/ /\\|/g')

which is used in

hardfp_defines_for = \
   $(shell echo $1 | \
     sed
's/\(.*\)\($(hardfp_mode_regexp)\)\($(hardfp_suffix_regexp)\|\)$$/-DFUNC=__&
-DOP_\1\3 -DTYPE=\2/')

So, it is difficult to use another regex.
