AC_CHECK_LIB broken with variable reference

AC_CHECK_LIB($foo, main) generates this line:

ac_ac_Lib=`echo "ac_cv_lib_$foo_main" | $ac_tr_sh`

This causes ac_ac_Lib to always be "ac_cv_lib_", since $foo_main is empty.

Note that this is a supported feature explicitly mentioned in the autoconf
docs (*Note (autoconf)Changed Results::).
