Log Message:
lint: fix handling of 'long double' in cross-compiled mode
When lint is compiled on x86-64 (where 'long double' has a 64-bit
mantissa) and targets arm (where 'long double' has a 53-bit mantissa),
warn if a constant cannot fit in the 'long double' of the target
platform, not of the host platform.
