These headers are required in order to build the bootstrap tools on macOS and Linux. A follow-up commit will add implementations of functions that don't exist on those operating systems to -legacy when bootstrapping. Reviewed By: brooks Differential Revision: https://reviews.freebsd.org/D14316

/*
|
|
* Work around error: initializer element is not a compile-time constant
|
|
*
|
|
* In some glibc versions (e.g. 2.28) htole16() expands to a call to an inline
|
|
* function. Clang will complain that this is not a compile time constant if
|
|
* it is used as a global struct initializer.
|
|
* Define them as simple macros instead. This is not quite as good since it
|
|
* won't catch any type errors when calling the macro (e.g. it now happily
|
|
* accepts pointers) but for the purpose of bootstrapping some tools this
|
|
* should be fine.
