Jeff Epler	2af0c52a91	lib/libm_dbl: Allow building when DBL_EPSILON is defined in <float.h>. ... This is the case in arm-none-eabi-gcc 14.2.1 (debian trixie). This fixes a diagnostic like: ../../lib/libm_dbl/libm.h:92:9: error: "DBL_EPSILON" redefined [-Werror] /usr/lib/gcc/arm-none-eabi/14.2.1/include/float.h:114:9: note: this is the location of the previous definition when building MPS2_AN500 (qemu port).

Alessandro Gatti	3613ad9624	lib/libm: Do not force floating point type size evaluation. ... Since C99, `FLT_EVAL_METHOD` should be left for the compiler/libc to define. Its redefinition breaks compilation with picolibc as the target's libc, since it defines said symbol in math.h before the libm define is evaluated by the compiler. In its place, there is a check to make sure floating point type sizes are what are expected to be, triggering a compilation error if those assumptions are no longer valid.
