/*
 * 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.
