+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.
