Architecture using soft float don't support the math FE_* exceptions.
This commit adds a patch to conditionnally build the FE_* exception
handling.

Subject: [PATCH] box-drawings: handle architecture with soft-float
|
|
|
|
Currently, architecture using soft-floats doesn't support instructions
|
|
FE_INVALID, FE_DIVBYZERO, FE_OVERFLOW and FE_UNDERFLOW and so building
|
|
on those architectures results with a build error.
|
|
As the sqrt math function should set errno to EDOM if an error occurs,
|
|
fetestexcept shouldn't be mandatory.
|
|
|
|
This commit removes the float environment error handling.
