Description of problem:
Dynamic linking of for packages with executables is failing
when using ghc-7.10.3 on aarch64 (and armv7hl).

eg1:
Linking dist/build/darcs/darcs ...
/builddir/build/BUILD/darcs-2.12.2/darcs-2.12.2/dist/build/libHSdarcs-2.12.2-5w02tFeyqS4LTTczMtN7Ff-ghc7.10.3.so:
error: undefined reference to 'log'
/usr/lib64/ghc-7.10.3/text_HmqVQnZSpjaC156ABqPhne/libHStext-1.2.2.1-HmqVQnZSpjaC156ABqPhne-ghc7.10.3.so:
error: undefined reference to 'logf'
collect2: error: ld returned 1 exit status

eg2:
Linking dist/build/xmobar/xmobar ...
/usr/lib64/ghc-7.10.3/scien_3vmCXiZeJinKZBcLawS8i0/libHSscientific-0.3.4.7-3vmCXiZeJinKZBcLawS8i0-ghc7.10.3.so:
error: undefined reference to 'log'
collect2: error: ld returned 1 exit status

eg3:
Linking dist/build/agda/agda ...
/usr/lib64/ghc-7.10.3/Quick_6TxL5Cx3o2p0HsyT59KWiD/libHSQuickCheck-2.8.2-6TxL5Cx3o2p0HsyT59KWiD-ghc7.10.3.so:
error: undefined reference to 'log'
/usr/lib64/ghc-7.10.3/text_HmqVQnZSpjaC156ABqPhne/libHStext-1.2.2.1-HmqVQnZSpjaC156ABqPhne-ghc7.10.3.so:
error: undefined reference to 'logf'
/builddir/build/BUILD/Agda-2.4.2.5/Agda-2.4.2.5/dist/build/libHSAgda-2.4.2.5-Inys1Zrl83YKq4l2eRqqZo-ghc7.10.3.so:
error: undefined reference to 'sqrt'
collect2: error: ld returned 1 exit status

How reproducible:
100%

Steps to Reproduce:
1. build packages with dynlinked executable

Actual results:
fails with "undefined reference to 'log'" etc.

Expected results:
dynlinking to work

Additional info:
This worked earlier though, eg in beginning of August 2016:
