Is this better?

    if test -n "$BREW"; then
      BREW_LIBGCCJIT_PREFIX=`$BREW --prefix --installed libgccjit 2>/dev/null`
      if test "$BREW_LIBGCCJIT_PREFIX"; then
        brew_libdir=`find ${BREW_LIBGCCJIT_PREFIX}/ -name \*.so \
                     | sed -e '1!d;s|/[[^/]]*\.so$||'`
        CFLAGS="$CFLAGS -I${BREW_LIBGCCJIT_PREFIX}/include"
        LDFLAGS="$LDFLAGS -L${brew_libdir} -I${BREW_LIBGCCJIT_PREFIX}/include"
