Hello all,
thanks much for all the answers!
To summarize: configure does check for nm ("checking for BSD-compatible
nm... /usr/bin/arm-linux-nm -B"), but doesn't set it in Makefile.in (I
did regenerate all files). I can live with AC_SUBST. Regarding BUILD_CC,
I guess I'll have to hack AC_PROG_CC.
With kind regards,
Baurzhan.
