+Subject: [PATCH] x86: Fix linking u-boot with ld.lld
+
+When linking the final u-boot binary with LLD, the following link errors
+are seen:
+
+ld.lld: error: can't create dynamic relocation R_386_32 against local
+               symbol in readonly segment; recompile object files with
+               -fPIC or pass '-Wl,-z,notext' to allow text relocations
+               in the output
+>>> defined in arch/x86/cpu/start.o
+>>> referenced by arch/x86/cpu/start.o:(.text.start+0x32)
+[...]
+>>> defined in arch/x86/cpu/start16.o
+>>> referenced by arch/x86/cpu/start16.o:(.start16+0x1C)
+
+According to Nick Desaulniers:
+
+"This is a known difference between GNU and LLVM linkers; the GNU
+ linkers permit relocations in readonly segments (making them not read
+ only), LLVM does not (by default)."
+
+Since U-Boot apparently seems to use relocations in readonly segments,
+change the global linker flags to permit them when linking with LLD by
+specifying '-z notext'.
