Upstream-Status: Inappropriate [SDK specific]
|
|
|
|
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.
