The maximum shebang line is indeed limited by the kernel to 128
characters:

I don't quite understand why building inside docker leads to longer path
names though?

You could try changing the definition of MESON in package/pkg-meson.mk
to be:

MESON = PYTHONNOUSERSITE=y $(HOST_DIR)/bin/python3 $(HOST_DIR)/bin/meson

But there may be other similar issues elsewhere.
