4 | Subject: [PATCH 01/15] binutils-crosssdk: Generate relocatable SDKs | ||
5 | |||
6 | This patch will modify the ELF linker scripts so that the crosssdk | ||
7 | linker will generate binaries with a 4096 bytes PT_INTERP section. When the binaries | ||
8 | will be relocated, at SDK install time, the interpreter path can be easily | ||
9 | changed by the relocating script. | ||
10 | |||
11 | Upstream-Status: Inappropriate [SDK specific] | ||
