perl fails to build on MIPS and VAX

[John Klos <john%klos.com@localhost>]

NetBSD-6, both recent, trying to build perl 5.22. First, VAX:

gcc -c    -O1 -fgcse -fstrength-reduce -fgcse-after-reload -pthread

-I/usr/local/include -D_FORTIFY_SOURCE=2 -DSTRUCT_TM_HASZONE -Wall -Wextra 
-Wc++-compat -Wwrite-strings -O1 -fgcse -fstrength-reduce 
-fgcse-after-reload -pthread -I/usr/include    -DVERSION=\"1.53\" 
-DXS_VERSION=\"1.53\" -DPIC -fPIC "-I../.."   POSIX.c
