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.
