x86/EFI: work around GNU ld 2.36 issue

Our linker capability check fails with the recent binutils release's ld:

.../check.o:(.debug_aranges+0x6): relocation truncated to fit: R_X86_64_32 against `.debug_info'
.../check.o:(.debug_info+0x6): relocation truncated to fit: R_X86_64_32 against `.debug_abbrev'
.../check.o:(.debug_info+0xc): relocation truncated to fit: R_X86_64_32 against `.debug_str'+76
.../check.o:(.debug_info+0x11): relocation truncated to fit: R_X86_64_32 against `.debug_str'+d
.../check.o:(.debug_info+0x15): relocation truncated to fit: R_X86_64_32 against `.debug_str'+2b
.../check.o:(.debug_info+0x29): relocation truncated to fit: R_X86_64_32 against `.debug_line'
.../check.o:(.debug_info+0x30): relocation truncated to fit: R_X86_64_32 against `.debug_str'+19
.../check.o:(.debug_info+0x37): relocation truncated to fit: R_X86_64_32 against `.debug_str'+71
.../check.o:(.debug_info+0x3e): relocation truncated to fit: R_X86_64_32 against `.debug_str'
.../check.o:(.debug_info+0x45): relocation truncated to fit: R_X86_64_32 against `.debug_str'+5e
.../check.o:(.debug_info+0x4c): additional relocation overflows omitted from the output

Tell the linker to strip debug info as a workaround. Debug info has been
getting stripped already anyway when linking the actual xen.efi.
