Patch to make MRI/Ruby safe for -pg

Subject: [PATCH] Suppress SIGPROF
We don't handle it well -- the exact reason is unclear, but threading
seems to trigger it -- so just squelch it.
Building with -pg is necessary for getting call-graph information with
e.g. the Linux 'perf' profiler. But -pg also causes the libc startup

Noto CJK font fix

<!--
Problem: After installing the Noto fonts (on my Debian `stretch`
system, with `apt install fonts-noto`), Japanese text in my
browser ends up displayed in the "Medium" style of the font
rather than the "Regular" style. The "Medium" style is too
heavy for normal text.

Python benchmarks for nixpkgs
View # Python nixpkgs benchmarks
These are benchmark results from the "pyperformance" benchmark suite:
https://pyperformance.readthedocs.io/
on CPython built with various options for optimization.
For context, including the specific optimizations involved, see:

# Scaffold to build just one package with modified stdenv scripts.
#
# Dependencies come unmodified from <nixpkgs>, including the stdenv's
# toolchain. This is useful for (a) iterating quickly on changes to
# stdenv scripts (like setup.sh), and (b) more easily comparing the
# build log against a baseline, by keeping inputs' paths the same so
# that any changes caused by changes in the scripts' behavior stand out.
