GSoC 2019: POSIX Compliance - FENV Environment probably not working properly in RISCV

[Vaibhav Gupta]

Configure command I used to build BSP:
==============================================
$ /home/varodek/development/rtems/kernel/rtems/configure
--prefix=/home/varodek/development/rtems/5 --enable-maintainer-mode
--target=riscv-rtems5 --enable-rtemsbsp=rv32imac --enable-tests
--enable-posix --disable-networking --enable-cxx RISCV_ENABLE_HTIF_SUPPORT=1
==============================================
.
.
.
.
Qemu command I used to run test:
==============================================
$ qemu-system-riscv32 -no-reboot -nographic -machine virt -m 256M -kernel
psxfenv01.exe
==============================================
.
.
.
.
Makefile.am
==============================================
+ if TEST_psxfenv01
+ psx_tests += psxfenv01
+ psxfenv01_SOURCES = psxfenv01/init.c
+ psxfenv01_CPPFLAGS = $(AM_CPPFLAGS) $(TEST_FLAGS_psxfenv01) \
+       $(support_includes)
+ psxfenv01_LDADD = -lm $(LDADD)
+ endif
+
==============================================
