To Reproduce undefined reference to `mpfr_get_q'

Expected behavior cross compile success

Screenshots

Desktop (please complete the following information):

• OS:WSL ubuntu16.04
• compiler [e.g. gcc 6.4, icc 19.0]
• BLAS and LAPACK library, if applicable
• Version [e.g. 22]

Additional context i had saw some problem about the mpfr_get_q,the anwser is low version mpfr,but my mpfr version is above 4.0

forget see libmpfr version,this is a Screenshots.and readelf libmpfr.so can not see mpfr_get_q function, you can see the first picture

You must be linking against an old version of libmpfr, because mpfr_get_q appears in the latest MPFR library but not in older ones.
