/*
* The .MIPS.abiflags section must be defined with the FP ABI flags set
* to 'any' to be able to link with both old and new libraries.
* Newer toolchains are capable of automatically generating this, but we want
* to work with older toolchains as well. Therefore, we define the contents of
* this section here (under different names), and then genvdso will patch
* it to have the correct name and type.
*
* We base the .MIPS.abiflags section on preprocessor definitions rather than
* CONFIG_* because we need to match the particular ABI we are building the
* VDSO for.
*
* See https://dmz-portal.mips.com/wiki/MIPS_O32_ABI_-_FR0_and_FR1_Interlinking
* for the .MIPS.abiflags section description.
