# Workaround for a build failure when building with MACHINE=qemuarm64. I think
# aarch64 is supposed to support NEON just fine, but building for qemuarm64
# fails in NEON code:
#
# .../speexdsp-1.2rc3/libspeexdsp/resample_neon.h:148:5: error: impossible constraint in 'asm'
#      asm volatile ("  cmp %[len], #0\n"
#      ^
#
# I sent an email about the issue to speex-dev. At the time of writing there
# are no responses yet:

# speexdsp was split off from speex in 1.2rc2. Older versions of speex can't
