description:
make(1): rename conflicting global variables called 'error'

When compiling make in all-in-one mode, these variable names conflict.
They could have been merged into a single variable, but that would have
required to make it a global variable for the other modules as well.
The parse module has a similar variable called 'fatals'.  All these can
possibly be merged into a single variable, but not now.
