 After some more testing, it turns out only sudo can be fixed by adding
 "-Wl,-z,common-page-size=0x10000" to LDFLAGS.  An example hacky patch
 is attached.  It may be beneficial to add this flag globally so that
 other ports may also be fixed.
 
 On the other hand, the LDFLAGS trick doesn't work for gnupg2.  On a
 closer look, the gnupg2 doesn't have "-Wl,-z,relro" in its LDFLAGS.
 As gnats doesn't handle attachments well, I'll send a follow-up email
 to port-mips with full gnupg2 build log hoping it will be useful for
 debugging purposes.
