libdirs, lflags and inputs were fixed 64-slot arrays written with no
bound check; the 65th -L/-l flag (or input) wrote past the allocation
-> heap corruption. Size all three by argc instead, the true upper
bound since each argv slot yields at most one entry, mirroring cstage
cmd/w6l/main.c:63-67 (calloc(argc, ...)). Drop the now-dead maxinputs
"too many inputs" cap -- cstage has none, and argc-sizing makes it
unreachable.
Regenerates the w6l combined.ww. Table-driven 632 test reaches a lib
only via the Nth -L (N in {1,64,65,100,128}, both stages); pre-fix the
nflags=65 row fails (slot one past the 64-array).
