Re: $(NM)

[Baurzhan Ismagulov]

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.
