FYI, there is the according GCC issue + patch

>From the doc of
https://gcc.gnu.org/bugzilla/attachment.cgi?id=47114&action=diff
+@item -mdouble=@var{bits}
+@opindex mdouble
+Set the size (in bits) of the @code{double} type. Valid values for
+@var{bits} are 32 and 64. This option is only available if the compiler
+is configured with @code{--with-double=32} or with @code{--with-double=64},
+and the argument of @code{--with-double=} specifies the default layout of
+@code{double}.
+
+@item -mlong-double=@var{bits}
+@opindex mlong-double
+Set the size (in bits) of the @code{long double} type. Valid values for
+@var{bits} are 32 and 64. This option is only available if the compiler
+is configured with @code{--with-long-double=32} or with
+@code{--with-long-double=64}, and the argument of @code{--with-long-double=}
+specifies the default layout of @code{long double}.
