binutils: Let crosssdk gold linker generate 4096 btyes long .interp section

When gold is used as default linker in crosssdk e.g. when building SDK
binaries with LTO, the binaries do not have large enough .interp
section size and SDK relocation fails for those nativesdk binaries and libraries
which used gold for linking. This patch extends the .interp relaxation
fix to gold

+Subject: [PATCH 01/16] binutils-crosssdk: Generate relocatable SDKs
 
 This patch will modify the ELF linker scripts so that the crosssdk
 linker will generate binaries with a 4096 bytes PT_INTERP section. When the binaries
 will be relocated, at SDK install time, the interpreter path can be easily
 changed by the relocating script.
 
+generate larger .interp section for gold linker as well

 Upstream-Status: Inappropriate [SDK specific]
