Hi Oleg,

first of all, we have an LDC forum/NG 
(http://forum.dlang.org/group/ldc) which would be more 
appropriate for your question. The referenced LDC patch is 
derived from https://github.com/ldc-developers/ldc/pull/1317, 
which hasn't been merged yet (but will be in not-too-distant 
future).
As you haven't explicitly specified what your target platform is, 
I can only assume that it's 32-bit ARM. With a vanilla LDC, 
cross-compiling to ARM with its double-precision reals will only 
work correctly if your LDC host compiler uses double-precision 
reals too, which isn't the case for Linux x86(_64), but for 
Windows. My LDC PR would make it work with a non-Windows x86(_64) 
host too, but only if the target (not the host) uses at most 
double-precision reals.
