Comment (by Jörg Krause):

 We recently bumped the boost version from 1.61.0 to 1.63.0 in Buildroot.
 Now, we get build errors for two architectures which were compiling
 successfully before: SH4 and OR1K. Both use a uclibc-toolchain.

 I've checked out the branch `topic/11756-non-standards-fpexception-intel`
 of the test module, it does not build either.

 At least, the SH4 toolchain does not have fenv.h. I did not checked to
 OR1K toolchain, yet.

 Here are some macros I've checked using the branch 11756:
 * `BOOST_NO_FENV_H` ''is defined''
 * `BOOST_SEH_BASED_SIGNAL_HANDLING` ''is not defined''
 * `BOOST_TEST_FPE_SUPPORT_WITH_GLIBC_EXTENSIONS__` ''is defined''
