clvmd: Fix stack overflow on 64 bit ARM

Seems the amount of allocated data on stack is dependent on page size.
As the page size on aarch64 is 64kiB writing to memory allocated by
alloca results in stack overflow as at the time of allocation the are
already 2 pages allocated. Clearly 128kiB is not sufficient and at least
3 pages are needed.

-# SYNOPSIS
-#
-#   AX_GCC_BUILTIN(BUILTIN)
-#
-# DESCRIPTION
-#
-#   This macro checks if the compiler supports one of GCC's built-in
-#   functions; many other compilers also provide those same built-ins.
-#
-#   The BUILTIN parameter is the name of the built-in function.
-#
-#   If BUILTIN is supported define HAVE_<BUILTIN>. Keep in mind that since
-#   builtins usually start with two underscores they will be copied over
-#   into the HAVE_<BUILTIN> definition (e.g. HAVE___BUILTIN_EXPECT for
-#   __builtin_expect()).
-#
-#   The macro caches its result in the ax_cv_have_<BUILTIN> variable (e.g.
-#   ax_cv_have___builtin_expect).
-#
-#   The macro currently supports the following built-in functions:
-#
-#    __builtin_assume_aligned
-#    __builtin_bswap16
-#    __builtin_bswap32
-#    __builtin_bswap64
-#    __builtin_choose_expr
-#    __builtin___clear_cache
-#    __builtin_clrsb
-#    __builtin_clrsbl
-#    __builtin_clrsbll
-#    __builtin_clz
-#    __builtin_clzl
-#    __builtin_clzll
-#    __builtin_complex
-#    __builtin_constant_p
-#    __builtin_ctz
-#    __builtin_ctzl
-#    __builtin_ctzll
-#    __builtin_expect
-#    __builtin_ffs
-#    __builtin_ffsl
-#    __builtin_ffsll
-#    __builtin_fpclassify
-#    __builtin_huge_val
-#    __builtin_huge_valf
-#    __builtin_huge_vall
-#    __builtin_inf
-#    __builtin_infd128
-#    __builtin_infd32
-#    __builtin_infd64
-#    __builtin_inff
-#    __builtin_infl
-#    __builtin_isinf_sign
-#    __builtin_nan
-#    __builtin_nand128
-#    __builtin_nand32
-#    __builtin_nand64
-#    __builtin_nanf
-#    __builtin_nanl
-#    __builtin_nans
-#    __builtin_nansf
-#    __builtin_nansl
-#    __builtin_object_size
-#    __builtin_parity
-#    __builtin_parityl
-#    __builtin_parityll
-#    __builtin_popcount
-#    __builtin_popcountl
-#    __builtin_popcountll
-#    __builtin_powi
-#    __builtin_powif
-#    __builtin_powil
-#    __builtin_prefetch
-#    __builtin_trap
-#    __builtin_types_compatible_p
-#    __builtin_unreachable
-#
-#   Unsuppored built-ins will be tested with an empty parameter set and the
-#   result of the check might be wrong or meaningless so use with care.
