Alex Crichton 90911d7259 Remove jemalloc from the runtime
As discovered in #9925, it turns out that we weren't using jemalloc on most
platforms. Additionally, on some platforms we were using it incorrectly and
mismatching the libc version of malloc with the jemalloc version of malloc.

Additionally, it's not clear that using jemalloc is indeed a large performance
win in particular situtations. This could be due to building jemalloc
incorrectly, or possibly due to using jemalloc incorrectly, but it is unclear at
this time.

Until jemalloc can be confirmed to integrate correctly on all platforms and has
verifiable large performance wins on platforms as well, it shouldn't be part of
the default build process. It should still be available for use via the
LD_PRELOAD trick on various architectures, but using it as the default allocator
for everything would require guaranteeing that it works in all situtations,
which it currently doesn't.

Closes #9925

# This is a procedure to define the targets for building
# the runtime.
#
# Argument 1 is the target triple.
#
# This is not really the right place to explain this, but
# for those of you who are not Makefile gurus, let me briefly
# cover the $ expansion system in use here, because it
# confused me for a while! The variable DEF_RUNTIME_TARGETS
# will be defined once and then expanded with different
# values substituted for $(1) each time it is called.
# That resulting text is then eval'd.
#
# For most variables, you could use a single $ sign. The result
# is that the substitution would occur when the CALL occurs,
# I believe. The problem is that the automatic variables $< and $@
# need to be expanded-per-rule. Therefore, for those variables at
# least, you need $$< and $$@ in the variable text. This way, after
# the CALL substitution occurs, you will have $< and $@. This text
# will then be evaluated, and all will work as you like.
#
# Reader beware, this explanantion could be wrong, but it seems to
# fit the experimental data (i.e., I was able to get the system
# working under these assumptions).
# Hack for passing flags into LIBUV, see below.
