Fix ubsan error in opts-global.cc

Fixes:
opts-global.cc:75:15: runtime error: store to address 0x00000bc9be70 with insufficient space for an object of type 'char'
which happens when mask == 0, len == 0 and we allocate zero elements.
Eventually, result[0] is called which triggers the UBSAN.

gcc/ChangeLog:

* opts-global.cc (write_langs): Allocate at least one byte.
