Bug#762485: geographiclib: FTBFS on 32-bit architectures: symbols not quite as expected

[Aaron M. Ucko]

Source: geographiclib
Version: 1.37-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Builds of geographiclib for all 32-bit architectures have been failing
because they yield different (mangled) symbol names than expected, as
detailed at

https://buildd.debian.org/status/logs.php?pkg=geographiclib&ver=1.37-1

Could you please account for these differences?

Thanks!
