On cross-compile builds, configure will look for a host-specific compiler by

prepending the user-provided host triple to the required binary name.

On iOS, this results in binaries like "arm64-apple-ios13.0-simulator-gcc",
#
which isn't a binary that exists, and isn't very convenient, as it contains the
#
iOS version. As the default cross-compiler name won't exist, configure falls
#
back to gcc, which *definitely* won't work. We're providing wrapper scripts for
#
these tools; the binary names of these scripts are better defaults than "gcc".
#
This only requires that the user put the platform scripts folder (e.g.,
#
"iOS/Resources/bin") in their path, rather than defining platform-specific
#
names/paths for AR, CC, CPP, and CXX explicitly; and if the user forgets to
#
either put the platform scripts folder in the path, or specify CC etc,

configure will fail.

Some systems cannot stand _XOPEN_SOURCE being defined at all; they
#
disable features if it is defined, without any means to access these
#
features as extensions. For these systems, we skip the definition of
#
_XOPEN_SOURCE. Before adding a system to the list to gain access to
#
some feature, make sure there is no alternative way to access this
#
feature. Also, when using wildcards, make sure you have verified the
#
need for not defining _XOPEN_SOURCE on all systems matching the
#
wildcard, and that the wildcard does not include future systems
#
(which may remove their limitations).
