Port abseil to GNU/Hurd.hurd
abseil has failed to build on GNU/Hurd for a long time. Now
let's make it work! :)
Note that `__GNU__` is the macro for detecting GNU/Hurd. And
`__MACH__` is also defined there besides on Apple platform.
They are both "mach" but with different implementation and
platform details. Here are the works,
* Mark platform features (not) supported by GNU/Hurd.
* Supports `mmap` and `write`.
* Not supports `vdso`. It's specific to Linux.
* Not supports `ELF_SYMBOLIZE` for now. GNU/Hurd uses ELF as
the binary format. But symbolizing in abseil relies on
reading object file path from `/proc/self/task/<pid>/maps`
(Linux specific) or `/proc/self/maps`. GNU/Hurd does have
the latter. However, due to its micro-kernel design, it's
currently unable to get the file path info there.
* Disable stack consumption measurement. The problem behind
it is that GNU/Hurd uses a very different way to implement
signal handling. Due to compiler behavior, it is
impossible to get a stable, valid and reliable statictic
data. In my test environment, it's 96 bytes (< 100) for
current codes.
* GNU/Hurd uses different errno and messages than Linux. So
related things are adjusted accordingly.
* Fix a misuse of `__MACH__`, which should actually be
`__APPLE__`.
* Fix a missing including of `signal.h` for using `SIGABRT`.
Otherwise compilation will fail with undefined symbol error
on GNU/Hurd.
