New kernel compatibility; obstack; pthread_getname_np The gcompat loader compiled as a static binary doesn't work on Linux since [a4ff8e8620d3f4](https://github.com/torvalds/linux/commit/a4ff8e8620d3f4f50ac4b41e8067b7d395056843), failing with an error like: ``` [349055.473655] 13325 (cmake): Uhuuh, elf segment at 0000000000400000 requested but the memory is mapped already ``` This is because the actual binary we want to run is also loaded at 0x400000. While it's actually okay to overlap the binary, since we're going to call `execve` again, the kernel doesn't allow the overlap anymore. Fix that by compiling the loader as static PIE, so it can be put at a different address. Also add `pthread_getname_np` and the option to link `obstack`. See merge request !4

- Respect user CFLAGS and LDFLAGS consistently. - Consistent use of curly braces for variables over parentheses. - Sort flags, putting '-o' at the end for readability of `make` output. - -fPIE doesn't mean anything to the linker Signed-off-by: Samuel Holland <samuel@sholland.org>

2018-04-03math: implement most of glibc's __*_finite functionsElizabeth Myers1-2/+1090
These are supposed to be specialisations for speed, but these are just faked. Some warnings were added too, if they return infinite values. As a side effect of this change, scalbl is also now implemented. As noted, not all functions are implemented; the big two blockers are an implementation of j0l and y0l; I imagine Bessel functions aren't too widely used, so I doubt that many things will want them. Someone (not it) can implement them later.
2018-04-03GCOMPAT__assert_with_reason: omit format parameterElizabeth Myers1-2/+2
__VA_ARGS__ expects one or more arguments; this is a cheesy hack to allow passing only a format string (which is often all you need for small asserts).
