with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
On vanilla gcc-10 (and gcc-9 -fno-common) build fails as:
```
../libtool --tag=CC --mode=link gcc ... -o libomxil-bellagio.la ...
ld: .libs/libomxil_bellagio_la-omx_reference_resource_manager.o:(.bss+0x18):
multiple definition of `globalIndex';
.libs/libomxil_bellagio_la-st_static_component_loader.o:(.bss+0x358):
first defined here
```
Upstream gcc-10 changed the default from -fcommon to fno-common:
https://gcc.gnu.org/PR85678.
The error also happens if CFLAGS=-fno-common passed explicitly.
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
In line with the Nixpkgs manual.
A mechanical change, done with this command:
find pkgs -name "*.nix" | \
while read f; do \
sed -e 's/description\s*=\s*"\([a-z]\)/description = "\u\1/' -i "$f"; \
done
I manually skipped some:
* Descriptions starting with an abbreviation, a user name or package name
* Frequently generated expressions (haskell-packages.nix)
