New jemalloc breaks mipsn64 (the 64bit userland)

Hey folks,

the recent switch to newer jemalloc in libc causes my 64bit userland
(evbmipsn64-eb) to break big time, I get coredumps from most binaries
including sshd and login.


The obvious change between both versions is the default minimum alignment:

Old code had

#define LG_QUANTUM 3

unconditionally for mips (so jemalloc guarantees 2^3 bytes alignment for
all allocations).

New code does:

#  ifdef __mips__
#    if defined(__mips_n32) || defined(__mips_n64)
#      define LG_QUANTUM                4
#    else
#      define LG_QUANTUM                3
#    endif
#  endif


so in my case alignment should increase from 2^3 to 2^4. But I don't see
how an increased default alignement could break things.

I will try to get more info out of the cores with a cross-gdb, but need
to extract the files first...

Any ideas?
