Bionic libc ships with `ioctl` that has two signatures, one with an
unsigned `request` parameter and one with a signed request parameter.
This leads to compilation failing due to `__typeof__(ioctl)` being used
by DRM which fails to resolve which overload to use, this has been fixed
by defining `BIONIC_IOCTL_NO_SIGNEDNESS_OVERLOAD` on Android.

There is an excellent writeup explaining this requirement here:

In short, for mixed environments such as the Steam Runtime and other
container-like environments, choosing which libdrm to link into the
client's address space is a hard problem. If the runtime has a newer
libdrm than the host, then it should be preferred, because the client
may be using newly-added symbols. But if the host has a newer libdrm,
then that should be used, because drivers may be depending on those.
Bumping the DSO minor version is transparent to all users because apps
only link against the major version, e.g. DT_NEEDED libdrm.so.2; the
fact that libdrm.so.2 is a link to libdrm.so.2.122.0 is a detail known
only to the loader, but it does let a smart runtime make better
decisions.

The endianness of the target is currently determined based on
preprocessor symbols. Unfortunately some symbols checked are wrong
(sparc64-linux-gnu-gcc does not define __BIG_ENDIAN__ or SPARC), and
several checks for big-endian architectures are missing.
Fix this by introducing a new preprocessor symbol HAVE_BIG_ENDIAN, which
is set based on meson's knowledge of the target endianness.
Android.common.mk does not need an update, as Android is always
little-endian (https://developer.android.com/ndk/guides/abis.html).

To reduce the size and complexity of checks. require() allows combining
auto and enabled checks(), so that something like
```meson
x = get_option('feature')
y = false
if x.enabled()
if not condition
error(...)
endif
y = condition
endif
```
can be rewritten as:
```meson
y = get_option('feature').require(condition, error_message : ...).allowed()
```
require checks the condition, then if the feature is required it emits
an error with the given message otherwise it returns a disabled feature.
allowed then returns whether the feature is not disabled, and returns
that (ie, .allowed() == not .disabled()). This is especially helpful for
longer more complex conditions

There is a Vivante GC1000 gpu in LS2K1000 and LS7A1000.
LS7A1000 is a bridge chip made by Loongson corporation
which act as north and/or south bridge of loongson's
desktop and server level processor. It is equivalent
to RS780E or something like that. In fact, the company
use RS780E as bridge of LS3A3000 at its early stage,
but as RS780E is out of stock long long time ago, the
company have to made one by themself. More details can
be read from its user manual[1].
This bridge chip typically use with LS3A3000, LS3A4000
and LS3A5000.
LS3A3000 is 4 core 1.45gHz mips64r2 compatible cpu.
LS3A4000 is 4 core 1.8gHz mips64r5 compatible cpu.
LS3A5000 is 4 core 2.5gHz loongarch cpu, the company
acclaim that loongarch a new archtecture with its
instruction set is released[2].
LS2K1000 is a double core 1.0Ghz mips64r2 compatible SoC[3].
we need to enable it to test and developing driver on above
listed archtecture.
