make_set_make

From make.U:

Some versions of make set the variable MAKE. Others do not. This variable contains the string to be included in Makefile.SH so that MAKE is set if needed, and not if not needed. Possible values are: make_set_make=# # If your make program handles this for you, make_set_make=MAKE=$make # if it doesn't. I used a comment character so that we can distinguish a set value (from a previous config.sh or Configure -D option) from an uncomputed value.

Currently, this is only used by Linux, where nm --dynamic is *required* to get symbols from an ELF library which has been stripped, but nm --dynamic is *fatal* on an archive library. Maybe Linux should just always set usenm=false.
