    math/fftw3: Update to 3.3.11
    
    Clean up whitespace and order Makefile. Simplify some logic including
    removing -malign-double for i386, which could break programs linked to
    the quad library. Nothing uses quad, so it's moot keeping complicated
    logic for a Tier-2 platform.
    
    All supported versions of FreeBSD have <bsd.cpu.mk> with altivec support
    in MACHINE_CPU. Remove obsolete workaround.
    
    Add a few maintainer helper targets to make updates a bit easier.
    These automatically update SHLIB_VER_MIN variable in the Makefile and
    regenerate FFTW3LibraryDepends.cmake.in. After just bumping PORTVERSION
    and removing any existing PORTREVISION line, simply running:
    `make -C ${PORTSDIR}/math/fftw -DMAINTAINER_MODE maintainer-update`
    will take care of all of the pre-test tasks.
    
    MFH:            2026Q4
    (cherry picked from commit 2c75ab24ce68f5185a6ebcb2eda33ad0575ccaf8)
