jemalloc-dev is massive

[Mike Hommey]

Hi,

I just saw that even stripped, libjemalloc.so is massive: 234K on my
system. This size goes down to about 180K when using -ffunction-sections
-fdata-sections when compiling, and -Wl,--gc-sections when linking.
As a comparison, the fork we currently use in Firefox builds as
a 32K library.
There's also 74K (!) of .bss in jemalloc-dev, vs. <1K in the old Firefox
fork. That seems quite excessive.
