Add two patches to fix compile errors being repeatedly seen on OpenWrt CI.
The first is an upstream backport to fix this i386-related error:

-I./purgatory/arch/x86_64/include -I./util_lib/include -I./include -Iinclude

-c -MD -o purgatory/arch/i386/entry32-16.o purgatory/arch/i386/entry32-16.S
purgatory/arch/i386/entry32-16.S: Assembler messages:
purgatory/arch/i386/entry32-16.S:23: Error: 64bit mode not supported on `i386'.
The second addresses an error using basename() on musl libc:
kexec/arch/i386/x86-linux-setup.c: In function 'add_edd_entry':
kexec/arch/i386/x86-linux-setup.c:332:20: warning: implicit declaration of function 'basename' [-Wimplicit-function-declaration]

Subject: [PATCH] i386: improve basename() compatibility
|
|
|
|
Drop usage of glibc basename() in favour of a simpler implementation that
|
|
works across GNU and musl libc, and is similar to existing code in fs2dt.c.
|
|
|
|
This fixes compile errors seen building against musl.
