ath9k: fix antenna gain calculation
[openwrt.git] / toolchain / uClibc / patches-0.9.32 / 960-remove_eabi_oabi_selection.patch
1 Rely on the compiler to be properly setup for the default ABI.

3 When 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.
