Tested for qemuarm64 with multilib enabled:

1. set machine and enable multilib

	require conf/multilib.conf
	MULTILIBS = "multilib:lib32"
	MACHINE = "qemuarm64"
	DEFAULTTUNE:virtclass-multilib-lib32 = "armv7vethf-neon"

2. enable fortran and install to image

	FORTRAN:forcevariable = ",fortran"
	IMAGE_INSTALL:append = " gfortran lib32-gfortran"

3. build image and boot, run gfortran with option '-v' to verify
   math-vector-fortran.h has been pre-included

   for aarch64:

	/usr/libexec/gcc/aarch64-poky-linux/14.1.0/f951 hello.f95 -quiet
	-dumpdir a- -dumpbase hello.f95 -dumpbase-ext .f95 -mlittle-endian
	-mabi=lp64 -version -fintrinsic-modules-path /usr/lib/gcc/aarch64-poky-linux/14.1.0/finclude
	-fpre-include=/usr/lib/gcc/aarch64-poky-linux/14.1.0/finclude/math-vector-fortran.h
	-o /tmp/ccuPIzQY.s

   for arm:

	/usr/libexec/gcc/arm-pokymllib32-linux-gnueabi/14.1.0/f951 hello.f95
	-quiet -dumpdir a- -dumpbase hello.f95 -dumpbase-ext .f95
	-mfloat-abi=hard -mtls-dialect=gnu -marm -mlibarch=armv7ve+fp
	-march=armv7ve+fp -version -fintrinsic-modules-path /usr/lib/gcc/arm-pokymllib32-linux-gnueabi/14.1.0/finclude
	-fpre-include=/usr/lib/gcc/arm-pokymllib32-linux-gnueabi/14.1.0/finclude/math-vector-fortran.h
	-o /tmp/cc5pikK8.s
