[OE-core] [PATCH] glibc: add more Imagination Meta relocation to elf.h

glibc master added the EM_METAG tag but didn't add the relocation defines.
However the kernel tooling only checks for EM_METAG when defining its own values
so scripts/recordmcount ends up using R_META_* symbols without their definition.
Whilst the kernel can and should be fixed, this breaks all users of recordmcount
so patch elf.h to add the values.

+Subject: [PATCH] elf.h: add relocations for Imagination META
+
+Adding EM_METAG but not the relocations means the kernel doesn't compile as it
+guards its own declarations on the presence of EM_METAG.
