Root/toolchain/uClibc/patches-0.9.32/960-remove_eabi_oabi_selection.patch

1Rely on the compiler to be properly setup for the default ABI.

3When installing-headers, there are two cases:
4- NPTL: no issue, a cross-compiler is already expected
5- LinuxThreads: no issue, EABI/OABI has no impact on installed headers.

26- If you say 'y' here, functions and constants required by the
27- ARM EABI will be built into the library. You should say 'y'
28- if your compiler uses the ARM EABI, in which case you will also
29- need a kernel supporting the EABI system call interface.

31- If you say 'n' here, then the library will be built for the
