7 config BR2_TOOLCHAIN_EXTERNAL_LIB_C
8 string "The core C library from the external toolchain"
11 Specify the core C shared library found in the external
12 toolchain. This is required in addition to any other
13 libraries to be copied.
15 config BR2_TOOLCHAIN_EXTERNAL_LIBS
16 string "Libraries to copy from the external toolchain"
19 A space separated list of the shared libraries to be copied
20 from the external toolchain into the root filesystem. Only
21 the top-level name is needed, i.e. libc.so, libpthread.so as
22 the actual shared library symlinked to will be copied also.

91 bool "Use software floating point by default"
93 depends on BR2_arm || BR2_armeb || BR2_mips || BR2_mipsel || BR2_powerpc
95 If your target CPU does not have a Floating Point Unit (FPU) or a
96 kernel FPU emulator, but you still wish to support floating point
97 functions, then everything will need to be compiled with soft
98 floating point support (-msoft-float).
