Subject: sci-libs/libqalculate: Increase stack size on musl

Originally discovered through unittests, certain equations given to
libqalculate will result in a stack overflow, as witnessed using ASAN.

ASAN output example:

==8920==ERROR: AddressSanitizer: stack-overflow on address
0x7f6a6a4f4e38 (pc 0x7f6a6ab4b695 bp 0x7f6a6a4f6180 sp 0x7f6a6a4f4e00 T1)
    #0 0x7f6a6ab4b695 in MathStructure::merge_multiplication(
      MathStructure&, EvaluationOptions const&, MathStructure*,
      unsigned long, unsigned long, bool, bool)
      (/lib/libqalculate.so.23+0x54b695)
