Subject: [PATCH 01/15] 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.
|
|
|
|
Upstream-Status: Inappropriate [SDK specific]
