[Romain Naour <romain.naour@gmail.com>]

This doesn't compile with glibc 2.26 where reallocarray() as been introduced.

Fixes:
stage1flex-misc.o: In function `allocate_array':
misc.c:(.text+0x38f): undefined reference to `reallocarray'
stage1flex-misc.o: In function `reallocate_array':
misc.c:(.text+0xc8a): undefined reference to `reallocarray'
collect2: error: ld returned 1 exit status
