-Subject: [PATCH 2/2] include: fix 'ulong' definition on musl targets
-
-The build failure was originally reported on arm64-musl
-target at https://bugs.gentoo.org/703132. Here is the amd64-musl
-variant:
-
-```
-$ LANG=C make CROSS_COMPILE=x86_64-gentoo-linux-musl- tools-only_defconfig -j$(nproc)
-$ LANG=C make CROSS_COMPILE=x86_64-gentoo-linux-musl- tools-all            -j$(nproc)
-...
-In file included from tools/env/../../env/flags.c:7,
-                 from tools/env/env_flags.c:1:
-include/env.h:159:1: error: unknown type name 'ulong'; did you mean 'long'?
-  159 | ulong env_get_ulong(const char *name, int base, ulong default_val);
-      | ^~~~~
-      | long
-```
-
-Note: 'ulong' is not defined there.
-
-On glibc 'ulong' comes from <sys/types.h>:
-
-```c
-/* Old compatibility names for C types.  */
-typedef unsigned long int ulong;
-```
-
-On musl it comes from <sys/types.h> as well but from under different guards:
-
-```c
-typedef unsigned long u_long, ulong;
-```
-
-The change inlines 'ulong' define similar to 'uint' define.
