In custom, optimized tunings, the value should -be modified to more precisely describe the tuning. - -MIPSPKGSFX_FPU - The value is set to "" or "-nf", where "-nf" indicates -that the tune is using a non-floating point ABI. - -MIPSPKGSFX_ABI - This is used to specify an alternative ABI when the previous -values are not enough to distringuish the package. "-n32" is added when -building for N32 ABI. |
